soc/intel: Extend fsp_get_pch_reset_status() to all FSP APIs

This patch drops the assert check around
`FSP_MULTIPHASE_SI_INIT_RETURN_BROKEN` config to ensure
`fsp_get_pch_reset_status()` can be used by all other FSP APIs to know
the status of the pending reset.

As per recent debug it has been found that, FSP is accumulating all
platform resets and executing a single reset from FSP Notify Phase.
As coreboot skipped calling into the FSP Notify APIs hence, it might
have missed the scope to issue the platform reset.

Going forward coreboot needs to implement the corresponding logic to be
able to identify any pending platform reset request and execute to
complete the silicon initialization flow.

BUG=b:282266168
TEST=Able to build and boot google/rex.
