platform/x86: ISST: Allow reading core-power state on HWP disabled systems
When HWP (Hardware P-states) is disabled, dynamic SST features are
disabled. But user should still be able to read the current core-power
state, with legacy P-states. This will allow users to read current
configuration with static SST enabled from BIOS.
To address this, do not call disable_dynamic_sst_features() when the
request is for reading the state.
