The UEFI specification mandates that software uses the DescriptorSize returned
by the GetMemoryMap() function to find the start of each EFI_MEMORY_DESCRIPTOR
in the MemoryMap array. This allows for future expansion of the EFI_MEMORY_DESCRIPTOR.

* Fix name of 'device_type' and 'migrate' properties.
* Fix 'reg' property. It is supposed to contain the CPU MPIDR of the
CPU being described.
* Fix byte ordering of data in 'psci' node.
* Fix some problems regarding the size of data. In a number of places
it was assumed data would be 32-bits wide.

PrepareFdt() function was getting pretty fat and big functions are more
complex to understand and find the information one is looking for.
This patch extracts some code from PrepareFdt() function and put it
in some new functions.

PcdArmLinuxKernelFixedOffset is supposed to indicate the offset from
the beginning of the system memory at which the kernel will be loaded.
However, this PCD value is not used at all. Instead the kernel is loaded
just below a certain limit indicated by PCD value PcdArmLinuxKernelMaxOffset.
This patch deletes PCD value PcdArmLinuxKernelFixedOffset to avoid any
confusion.

This patch corrects a problem detecting uInitrd signature when booting
with FDT.
BdsBootLinuxFdt was attempting to read the signature from InitrdImage which
is zero at this point in the code. The code now reads the signature from
InitrdImageBase.

of using the numeric value directly in the code.

Because the D&I caches were clean before to be disabled, the cache
lines might have got dirty during the cache maintenance operations.
This fix disables D&I caches before to clean them. The performance
drops should be minimised as invalidating the I cache is only a
couple of instruction.
