Marek Behún b662232d18 drivers: marvell: comphy-a3700: fix USB3 powering on when on lane 2
When USB3 is on lane 2 and indirect register access is used, the polling
at the end of the mvebu_a3700_comphy_usb3_power_on function is
incorrect.

The LOOPBACK_REG0 register should not be used at all. Instead we have to
write the LANE_STATUS1 register address (with offset
USB3PHY_LANE2_REG_BASE_OFFSET) into the indirect address register and
then we should poll indirect data register.

This fixes problems on Turris Mox, which uses lane 2 for USB3.
