kernel: backports: mt7530: fix TRGMII mode after reset

Browse Source 
Backport upstream patch that fixes TRGMII mode now that mt7530 is
actually resetting the switch on ramips devices.

Patches apply to both Linux 5.4 and 5.10, since TRGMII is broken on both.

Fixes: 69551a2442 ("ramips: manage low reset lines")
