soc/intel/alderlake: Disable package C-state demotion for Raptor Lake

While executing S0ix tests on Raptor Lake boards, we observed CPU fails
to enter suspend state, causing failure.

As a workaround, disable package C-state demotion, till this issue
is fixed in ucode.

BUG=268296760
BRANCH=firmware-brya-14505.B
TEST=Boot and verified that S0ix issue is resolved.
