skylake: Do FspTempRamInit only for FSP1.1 & tidy up PCH early init

Prepare Skylake for FSP2.0 support.

We do not use FSP-T in FSP2.0 driver, hence guard the
FspTempRamInit call under a switch.

In addition to the current early PCH configuration
program few more register, so all in all we do the following,
* Program and enable ACPI Base.
* Program and enable PWRM Base.
* Program TCO Base.
* Program Interrupt configuration registers.
* Program LPC IO decode range.
* Program SMBUS Base address and enable it.
* Enable upper 128 bytes of CMOS.
And split the above programming into into smaller functions.

Also, as part of bootblock_pch_early_init we enable decoding
for HPET range. This is needed for FspMemoryInit to store and
retrieve a global data pointer.

And also move P2SB related definitions to a new header file.

TEST=Build and boot Kunimitsu
