Refactor the ARM CoreLink TZC-400 driver
TrustZone protection can be programmed by both memory and TrustZone
address space controllers like DMC-500 and TZC-400. These peripherals
share a similar programmer's view.
Furthermore, it is possible to have multiple instances of each type of
peripheral in a system resulting in multiple programmer's views.
For example, on the TZC-400 each of the 4 filter units can be enabled
or disabled for each region. There is a single set of registers to
program the region attributes. On the DMC-500, each filter unit has its
own programmer's view resulting in multiple sets of registers to program
the region attributes. The layout of the registers is almost the same
across all these variations.
Hence the existing driver in `tzc400\tzc400.c` is refactored into the
new driver in `tzc\tzc400.c`. The previous driver file is still maintained
for compatibility and it is now deprecated.

Remove the assert for TZC base during initialization
When resuming from system suspend the TZC needs to be
re-initialized. Hence the assertion for TZC base address
to detect re-initialization is removed.

Fix TZC-400 peripheral detection
The TZC-400 driver implementation incorrectly uses the component
ID registers to detect the TZC-400 peripheral. As all ARM
peripherals share the same component ID, it doesn't allow to
uniquely identify the TZC-400 peripheral. This patch fixes the
TZC-400 driver by relying on the `part_number_0` and
`part_number_1` fields in the `PID` registers instead.
The `tzc_read_component_id` function has been replaced by
`tzc_read_peripheral_id`, which reads the 'part_number' values
and compares them with the TZC-400 peripheral ID.
Also, it adds a debug assertion to detect when the TZC driver
initialisation function is called multiple times.

Use uintptr_t as base address type in ARM driver APIs
This patch changes the type of the base address parameter in the
ARM device driver APIs to uintptr_t (GIC, CCI, TZC400, PL011). The
uintptr_t type allows coverage of the whole memory space and to
perform arithmetic operations on the addresses. ARM platform code
has also been updated to use uintptr_t as GIC base address in the
configuration.

Add TZC function to configure region 0
Region 0 is special in TZC-400. It is possible to set the access
permissions for this but not the address range or filters to which
the permissions apply. Add a function for setting the region 0
access permissions.
Also add some VERBOSE logging and allow assembly files to include
the TZC header.

Juno: Reserve some DDR-DRAM for secure use
This patch configures the TrustZone Controller in Juno to split
the 2GB DDR-DRAM memory at 0x80000000 into Secure and Non-Secure
regions:
- Secure DDR-DRAM: top 16 MB, except for the last 2 MB which are
used by the SCP for DDR retraining
- Non-Secure DDR-DRAM: remaining DRAM starting at base address
Build option PLAT_TSP_LOCATION selects the location of the secure
payload (BL3-2):
- 'tsram' : Trusted SRAM (default option)
- 'dram' : Secure region in the DDR-DRAM (set by the TrustZone
controller)
The MMU memory map has been updated to give BL2 permission to load
BL3-2 into the DDR-DRAM secure region.

Simplify interface to TZC-400 driver
The TZC-400 driver previously allowed the possibility of multiple
controller instances to be present in the same executable. This
was unnecessary since there will only ever be one instance.
This change simplifies the tzc_init() function to only take the
base address argument needed by implementation, conforming to the
driver initialization model of other drivers. It also hides some
of the implementation details that were previously exposed by the
API.
The FVP port has been updated accordingly.
THIS CHANGE REQUIRES ALL PLATFORM PORTS THAT USE THE TZC-400
DRIVER TO BE UPDATED

Reduce deep nesting of header files
Reduce the number of header files included from other header
files as much as possible without splitting the files. Use forward
declarations where possible. This allows removal of some unnecessary
"#ifndef __ASSEMBLY__" statements.
Also, review the .c and .S files for which header files really need
including and reorder the #include statements alphabetically.

Always use named structs in header files
Add tag names to all unnamed structs in header files. This
allows forward declaration of structs, which is necessary to
reduce header file nesting (to be implemented in a subsequent
commit).
Also change the typedef names across the codebase to use the _t
suffix to be more conformant with the Linux coding style. The
coding style actually prefers us not to use typedefs at all but
this is considered a step too far for Trusted Firmware.
Also change the IO framework structs defintions to use typedef'd
structs to be consistent with the rest of the codebase.

Move include and source files to logical locations
Move almost all system include files to a logical sub-directory
under ./include. The only remaining system include directories
not under ./include are specific to the platform. Move the
corresponding source files to match the include directory
structure.
Also remove pm.h as it is no longer used.
