bnxt_en: Add PTP clock APIs, ioctls, and ethtool methods
Add the clock APIs to set/get/adjust the hw clock, and the related
ioctls and ethtool methods.
v2: Propagate error code from ptp_clock_register().
Add spinlock to serialize access to the timecounter. The
timecounter is accessed in process context and the RX datapath.
Read the PHC using direct registers.
