soc/intel/alderlake: Refactor `pmc_lockdown_cfg` function

This patch refactors the `pmc_lockdown_cfg()` to remove the helper
functions and uses the `setbits32` function to enforce bit locking
as applicable.

BUG=b:211954778
TEST=Able to build google/redrix with these changes and boot to OS.
> localhost ~ # iotools mmio_read32 0xfe0018c4

0x85000000 (bit 31 is set)
> localhost ~ # iotools mmio_read32 0xfe001024

0x00062610 (bits 4, 17 and 18 are set)
