Subject: [PATCH net-next 02/21] net: stmmac: rk: get rid of rk_phy_power_ctl()

It is not worth having a common rk_phy_power_ctl() when the only
difference is which regulator function is called. Also, passing
true/false is non-descriptive. Split this function, moving the code
appropriately into rk_phy_powerup() and rk_phy_powerdown().
