soc/intel/skylake: switch to common ACPI code 

Use the common ACPI code to reduce code duplication.

After this change, `PSS_MAX_ENTRIES` is honored correctly in P-state
table generation (as of commit c2540a9) and the number reduces from 10
to 7 entries.

Also, remnants of P_BLK support missed in CB:58096 will vanish.

Tested on google/fizz: no errors in dmesg, ACPI tables remain the same
(except PSS, as mentioned above).
