net: phy: marvell-88q2xxx: Align soft reset for mv88q2110 and mv88q2220

The soft reset implementations for mv88q2110 and mv88q2220 differ as the
later need to consider that auto negation is supported on mv88q2220
devices. In preparation of enabling auto negotiation on mv88q2110 merge
the two rest functions into a device generic one.

The mv88q2220 behavior is kept as is but extended to wait for the reset
bit to be clears before continuing, as was done previously on mv88q2220.
