net: dsa: microchip: use dynamic mask to check pulse width validity
The pulse width validity is checked against an hardcoded mask. KSZ8463
uses a smaller register than other switches so this check won't work for
it.
Move the mask as a ksz_ptp_tou_pulse_verify()'s input to allow changing
it for KSZ8463 case.
