This fixes USB3 devices not being enumerated on beagle-x15 if usb was started in u-boot. We don't re-program SATA DPLL if it is locked as it was causing SATA failures if device was hotpluged after boot.

If bootloader has set a wrong DPLL then we must trash those values
and re-program it anyways. This fixes USB3 devices not being enumerated
on beagle-x15 if usb was started in u-boot.

We don't re-program SATA DPLL if it is locked as it was causing
SATA failures if device was hotpluged after boot.

Previously omap_control_phy_power() was used to power off the PHY during probe. But once PIPE3 driver is adapted to use syscon, omap_control_phy_power() cannot be used. Hence used ti_pipe3_power_off to power off the PHY. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Acked-by: Roger Quadros <rogerq@ti.com>
