bnxt: Defer PTP initialization to after querying function caps

Browse Source 
Driver uses the flag BNXT_FLAG_MULTI_HOST to determine whether
to use non-realtime mode PHC when running on a multi host NIC.
However when ptp initializes on a NIC with shared PHC, we still
don't have this flag set yet because HWRM_FUNC_QCFG is issued
much later.

Move the ptp initialization code after we have issued func_qcfg.
The next patch will use the BNXT_FLAG_MULTI_HOST flag during PTP
initialization.
