refactor(drivers/marvell/comphy-3700): simplify usage of sata power off

Browse source 
Function mvebu_a3700_comphy_sata_power_off() uses comphy_mode parameter
only for extracting mode bits. Mode is always COMPHY_SATA_MODE, so
there is no need to pass comphy_mode parameter to this function. Use
directly COMPHY_SATA_MODE in mvebu_a3700_comphy_sata_power_off().
