[PATCHv3 net-next] net: ag71xx: get reset control using devm api

Currently, the of variant is missing reset_control_put in error paths.
The devm variant does not require it.

Allows removing mdio_reset from the struct as it is not used outside the
function.

v2: don't call after ag71xx_mdio_probe. Already done.
v3: use devm instead.
