ptp: bnxt: convert .adjfreq to .adjfine
When the BNXT_FW_CAP_PTP_RTC flag is not set, the bnxt driver implements
.adjfreq on a cyclecounter in terms of the straightforward "base * ppb / 1
billion" calculation. When BNXT_FW_CAP_PTP_RTC is set, the driver forwards
the ppb value to firmware for configuration.
Convert the driver to the newer .adjfine interface, updating the
cyclecounter calculation to use adjust_by_scaled_ppm to perform the
calculation. Use scaled_ppm_to_ppb when forwarding the correction to
firmware.
