Cache maintenance operations by Set/Way require that the Write Buffer
be drained before the cache is flushed. Without that, the flush can
miss the most recent values written as they are still "pipelined".
That has unfortunate consequences, especially where code is being
copied to RAM.
The fix is to add DSB instructions before the affected operations.

Boot entries created by efibootmgr may contain a partial device path
to the EFI application to boot. These entries begin with a partition
device path whereas entries created via ARM Boot Manager contain a
full path to the EFI application. The ARM BDS code will fill in the
missing parts of this partial device path as it does for removeable
device paths. This allows the application to be loaded and started.
However, the current code passes the original partial device path to
gBS->LoadImage() and thus LoadImage is unable to find a DeviceHandle
for the path. This means the application being booted cannot find the
boot device from the Loaded Image Protocol structure. In the case of
grub, this prevents the grub config file from being found. This patch
fixes this by making sure the full path is propagated back to the
caller of gBS->LoadImage() so that a proper DeviceHandle gets passed
to the application being booted.

Update the LastBlockEntry return value when allocating a new page table block
and the parent page table entry is not valid. Discovered when producing page
table entries for a memory region that spans multiple page table entries of a
parent page table block. Not very memory space efficient because the rest of
the code could calculate a required page level that is deeper than some blocks
of the memory region might require. Case that found the problem:
MemoryRegion->VirtualBase = 0
MemoryRegion->Length = 0x7F000000
This fix will create an un-needed level of page table for address
range 0 -> 0x40000000

During the interrupt registration comparison is made against
max value of exception types for ARMV7, but in the common handling
function the check is made against max value of exceptions types
for ARMV8. This can lead to undefined behaviour during registration
of interrupts.
This patch modifies the registration function to handle only AArch64
exceptions.

'tlb alle1' was used to invalidate the TLBs in EL1. Expect this instruction can only
be invoked from EL2.
The correct instruction to invalidate TLBs in EL1 is 'tlbi vmalle1' - it invalidates
the TLBs of the current VMID.
