bnxt_en: Refactor bnxt_ptp_init()
[ Upstream commit 1e9614cd956268e10a669c0593e7e54d03d0c087 ]
Instead of passing the 2nd parameter phc_cfg to bnxt_ptp_init().
Store it in bp->ptp_cfg so that the caller doesn't need to know what
the value should be.
In the next patch, we'll need to call bnxt_ptp_init() in bnxt_resume()
and this will make it easier.
