TZC: rename included C file to a header
C files shouldn't be included into others. This file only contains some
macros and functions that can be made `static inline`, so it is ok to
convert it into a header file.
This is the only occurrence of a C file being included in another one in
the codebase instead of using a header, other occurrences are a way of
achieving backwards-compatibility.
Functions therein have been qualified as `inline`.

AArch32: Enable GIC and TZC support
This patch modifies GICv3 and TZC drivers to add AArch32 support.
No modifications are required for the GICv2 driver for AArch32 support.
The TZC driver assumes that the secure world is running in Little-Endian
mode to do 64 bit manipulations. Assertions are present to validate the
assumption.
Note: The legacy GICv3 driver is not supported for AArch32.

Use unsigned long long instead of uintptr_t in TZC400/DMC500 drivers
Currently the `tzc400_configure_region` and `tzc_dmc500_configure_region`
functions uses uintptr_t as the data type for `region_top` and `region_base`
variables, which will be converted to 32/64 bits for AArch32/AArch64
respectively. But the expectation is to keep these addresses at least 64 bit.
This patch modifies the data types to make it at least 64 bit by using
unsigned long long instead of uintptr_t for the `region_top` and
`region_base` variables. It also modifies the associated macros
`_tzc##fn_name##_write_region_xxx` accordingly.

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.
