This breaks MDIO on kswitch-d10, presumably because the global switch
reset is not released early enough anymore.

And maybe Microchip can chime in here and tell us what
subsystems in the SoC will actually be reset by this.
I fear this reset will affect almost every part of the
SoC. So it would have to be bound to every single
device? Or maybe adding that reset to the switch driver
was a mistake in the first place?

I mean, if it wouldn't be for the guard bit, it would
also reset the CPU core..
