phy: ti-pipe3: Program the DPLL even if it was already locked
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.
