mb/intel/adlrvp: Disable PM Timer for ADL-N

Keeping the PM timer enabled will disqualify an ADL system from entering
S0i3, and will also cause an increase in power during suspend states.
The PM timer is not required for ADL-N boards, therefore disabling it.

BRANCH=NONE
TEST=Build and boot ADL-N RVP. Verify system is entering S0i3 state.
