Revert "dt: add of_alias_scan and of_alias_get_id"
This reverts commit 750f463a749e28464151ad26938d11b07b1c43cb.
of_alias_* still needs work to be generalized for 'promtree' dt
platforms, and to no implicitly create entries for available ids.

dt: add of_alias_scan and of_alias_get_id
The patch adds function of_alias_scan to populate a global lookup

of/flattree: forward declare struct device_node in of_fdt.h
This patch forward declares struct device_node to fix a compile error
when of_fdt.h is included, but of.h is not. Alternately, including
linux/of.h could have been added to of_fdt.h, but that pulls in a lot
of unnecessary declarations when only working with the flattened
form.

of/flattree: Refactor unflatten_device_tree and add fdt_unflatten_tree
unflatten_device_tree has two dependencies on things that happen
during boot time. Firstly, it references the initial device tree
directly. Secondly, it allocates memory using the early boot
allocator. This patch factors out these dependencies and uses
the new __unflatten_device_tree function to implement a driver-visible
fdt_unflatten_tree function, which can be used to unflatten a
blob after boot time.
V2:
- remove extra __va() call
- make dt_alloc functions return void *. This doesn't fix the general
strangeness in this code that constantly casts back and forth between
unsigned long and __be32 *

of/flattree: Eliminate need to provide early_init_dt_scan_chosen_arch
This patch refactors the early init parsing of the chosen node so that
architectures aren't forced to provide an empty implementation of
early_init_dt_scan_chosen_arch. Instead, if an architecture wants to
do something different, it can either use a wrapper function around
early_init_dt_scan_chosen(), or it can replace it altogether.
This patch was written in preparation to adding device tree support to
both x86 ad MIPS.

This patch makes unflatten_device_tree() safe to call from any arch
setup code with the following changes:
- Make sure initial_boot_params actually points to a device tree blob
before unflattening
- Make sure the initial_boot_params->magic field is correct
- If CONFIG_OF_FLATTREE is not set, then make unflatten_device_tree()
an empty static inline function.
This patch also adds some additional debug output to the top of

of/flattree: use callback to setup initrd from /chosen
At present, the fdt code sets the kernel-wide initrd_start and
initrd_end variables when parsing /chosen. On ARM, we only set these
once the bootmem has been reserved.
This change adds an arch hook to setup the initrd from the device
tree:
void early_init_dt_setup_initrd_arch(unsigned long start,
unsigned long end);
The arch-specific code can then setup the initrd however it likes.
Compiled on powerpc, with CONFIG_BLK_DEV_INITRD=y and =n.
