armv8: layerscape: sata: refine port register configuration
Sata registers PP2C and PP3C are used to control the configuration
of the PHY control OOB timing for the COMINIT/COMWAKE parameters
respectively. Calculate those parameters from port clock frequency.
Overwrite those registers with calculated values to get better OOB
timing.
