net: stmmac: use correct PPS capture input index
The stmmac supports up to 4 auxiliary snapshots that can be enabled by
setting the appropriate bits in the PTP_ACR bitfield.
Previously as of commit f4da56529da6 ("net: stmmac: Add support for
external trigger timestamping") instead of setting the bits, a fixed
value was written to this bitfield instead of passing the appropriate
bitmask.
Now the correct bit is set according to the ptp_clock_request.extts_index
passed as a parameter to stmmac_enable().
