fix(intel): remove wfi polling when performing cpu on

Polling the WFI status produces vague result as
the secondary CPU will keep changing it's states.

Removing the polling WFI code as this will cause
polling timeout since the CPU state is uncertain.

The CPU ON function will still work by removing this
check.

fix(intel): update warm reset routine and bootscratch register usage

Agilex5 platform:
Boot scratch COLD6 register is meant for Customer use only.
So, use Intel specific COLD3 register with [5:2]bits to
determine the warm reset and SMP boot requests.
Also handle the unaligned DEVICE/IO memory store and load
in the assembly entrypoint startup code.

Agilex, Stratix10, N5X platforms:
Use only the LSB 4bits [3:0] of the boot scratch COLD6 register
to detect the warm reset request.

fix(intel): handle cold reset via physical reset switch

On the Agilex5 platform when cold reset is issued via CLI application
in the OS, it is received in the BL31 via a SMC call and handled
accordingly like flush/invalidate the caches. However, when the cold
reset is issued via an external switch these handlings are missed.
This patch addresses those missed cache operations.

Also, this patch is to restoring SCR_EL3 NS bit to its previous value
in order to avoid unintended behavior especially if subsequent code
expects the SCR_EL3 register to be in its original configuration.

fix(intel): add cache invalidation during BL31 initialization

During warm boot, the data cache is invalidated before
enabling them in u-boot proper, this cache
invalidation (+ cleaning) leads to the sync-up of stale
values in the cache to be synced with the main memory.
So, before the cache cleaning is done in u-boot proper,
it is invalidated in BL31 so that the cache data gets in
sync with u-boot proper memory address space and when
u-boot proper does its initialization which in turn clears
its BSS and heap section.
