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.
