ArmPkg/BdsLib: Linux kernel supports either FDT or ATAG
...
If a FDT blob is passed to the kernel it is required we can load it.
If we fail to load the binary then we must abort the Linux booting
process.

ArmPkg/CpuDxe: ZeroMem the gExceptionHandlers[] array

Prevent an IRQ (or any other exceptions) to make a call to an undefined
handler when the interrupt handler has not been registered yet.

ArmPkg/CpuDxe: Register a callback for the gIdleLoopEventGuid event
...
This gIdleLoopEventGuid event signals the Cpu that it should go into
the idle state waiting for any events.
CpuSleep() is used in this implementation to make the Cpu wait for
the next interrupt (WFI instruction).

ArmPkg/CpuDxe: Change chain of dependency for CpuDxe and PL390Gic
...
Previously the CPU driver had a dependency on the GIC driver.
But by design is should be the opposite. The CPU driver installs the
CPU protocol that exposes the exception registration function.
And then, the interrupt controller registers its IRQ handler through
this interface.

ArmPkg: Introduce ArmSetLowVectors/ArmSetHighVectors functions

These functions set/clear the SCTLR.V bit that controls the location
of the Vector Table.
This commit also forces the SCTLR.V to be clear when the VBAR register
is set.
Note: The original fix has been proposed by Eugene Cohen (HP).

ArmPkg: Introduce the PCD PcdDebuggerExceptionSupport

If no one has touched the exception vector prior to the CPU DXE then the Vector
might contain non zero data.
