ice: pass reset type to PTP reset functions
The ice_ptp_prepare_for_reset() and ice_ptp_reset() functions currently
check the pf->flags ICE_FLAG_PFR_REQ bit to determine if the current
reset is a PF reset or not.
This is problematic, because it is possible that a PF reset and a higher
level reset (CORE reset, GLOBAL reset, EMP reset) are requested
simultaneously. In that case, the driver performs the highest level
reset requested. However, the ICE_FLAG_PFR_REQ flag will still be set.
The main driver reset functions take an enum ice_reset_req indicating
which reset is actually being performed. Pass this data into the PTP
functions and rely on this instead of relying on the driver flags.
This ensures that the PTP code performs the proper level of reset that
the driver is actually undergoing.
