[PATCH] net: dsa: mt7530: increase reset hold time

[Justin Swartz]

Increase the MT7530 reset hold period from 1000-1100 usec
to 5000-5100 usec.

This should reduce the likelihood of an incorrect external
crystal frequency selection which may occur when reset is
deasserted too early under certain link conditions.
