Right now, every driver that provides a phy uses 'select GENERIC_PHY',
and they would have to keep doing that. This is not unlike what we
do for other silent symbols like MFD_CORE, REGMAP_I2C, or PINCTRL,
and it's not as problematic as 'select' on a user-visible option,
or (worst) mixing 'select' and 'depends on'.
