When the function that determines the size of a contiguous region
was returning from a sub-level table scanning it was forgetting to
move to the next entry of its own level table.

Accesses to system registers are disproportionately heavy-weight
when executed under virtualization, since each one involves two
world switches (from guest to host and back again).
So change the sequence that enables the GIC SRE interface so that
it performs only a single sysreg read to test whether the SRE
interface is enabled already, and only performs a write and an
additional read if that turns out not to be the case.

This removes the range size threshold for virtual address based cache
maintenance instructions that operate on VA ranges to be 'promoted' to
use set/way instructions.
Doing so is unsafe: set/way operations are fundamentally different
from VA operations, and really only suitable for cleaning or invalidating
a cache when turning it on or off.
To quote the ARM ARM (DDI0487A_d G3.4):
"""
Since the set/way instructions are performed only locally, there is no
guarantee of the atomicity of cache maintenance between different PEs,
even if those different PEs are each performing the same cache maintenance
instructions at the same time. Since any cacheable line can be allocated
into the cache at any time, it is possible for [a] cache line to migrate
from an entry in the cache of one PE to the cache of a different PE in a
manner that the cache line avoids being affected by set/way based cache
maintenance. Therefore, ARM strongly discourages the use of set/way
instructions to manage coherency in coherent systems.

gArmTokenSpaceGuid.PcdSystemMemoryBase
gArmTokenSpaceGuid.PcdSystemMemorySize
gArmTokenSpaceGuid.PcdFdBaseAddress
gArmTokenSpaceGuid.PcdFvBaseAddress
to include PcdsPatchableInModule. This makes the build system correctly
distinguish fixed PCDs from PCDs whose value may be different from the
assigned value at compile time.
Note that this only affects platforms that explicitly mark these PCDs as
PatchableInModule in the DSC. All existing platforms that use FixedPcd
will not be affected by this change.

The DT binding for the ARM generic timer describes the secure,
non-secure, virtual and hypervisor timer interrupts, respectively.
However, under virtualization, only the virtual timer is usable, and
the device tree may omit the hypervisor timer interrupt. (Other timer
interrupts cannot be omitted simply due to the fact that the virtual
timer is listed third)

But the stack pointer is decremented before writing to the stack.

This change ensures the total size declared by the device tree matches
the actual data (and not the over-allocated size value).

Even if the CPU id registers indicate hardware support for the
System Register interface to the GIC, higher exception levels
may disable that interface and only allow access through MMIO.
So move the enabling of the SRE bit to the GIC version detection
routine: if we trigger an exception, we would have anyway at a
later stage, so the net effect is the same. However, if setting
the bit doesn't stick, it means we can switch to MMIO and proceed
normally otherwise.

Both MicroSeconds and PcdArmArchTimerFreqInHz are 32-bit values on
AArch32 so their multiplication produces 32-bit result that might
cause wrong calculation.
Example: With MicroSeconds = 200 us, PcdArmArchTimerFreqInHz = 24MHz.
200*24000000 = 0x1_1E1A_3000 => So 0x1E1A_3000 when the type is UINT32.

Implement the resizing of the file with SetInfo().
Implement the renaming of a file with SetInfo().
Allow to seek past the end of a file.
The support of file resizing implies a rework of the read, write
and close functions. So does the support of seeking past the end
of a file. That why those two changes are done in the same patch.
