A recent change to MIPS ralink reset logic made it so mt7530 actually
resets the switch on platforms such as mt7621 (where bit 2 is the reset
line for the switch). That exposed an issue where the switch would not
function properly in TRGMII mode after a reset.
Reconfigure core clock in TRGMII mode to fix the issue.
Tested on Ubiquiti ER-X (MT7621) with TRGMII mode enabled.
