bnxt_en: Do not initialize PTP on older P3/P4 chips
[ Upstream commite8b51a1a15
] The driver does not support PTP on these older chips and it is assuming that firmware on these older chips will not return the PORT_MAC_PTP_QCFG_RESP_FLAGS_HWRM_ACCESS flag in __bnxt_hwrm_ptp_qcfg(), causing the function to abort quietly. But newer firmware now sets this flag and so __bnxt_hwrm_ptp_qcfg() will proceed further. Eventually it will fail in bnxt_ptp_init() -> bnxt_map_ptp_regs() because there is no code to support the older chips. The driver will then complain: "PTP initialization failed.\n" Fix it so that we abort quietly earlier without going through the unnecessary steps and alarming the user with the warning log.
