Subject: [PATCH V4 5/8] SPEAr13xx: Fixup: Move SPEAr1340 SATA platform code to phy driver
ahci driver needs some platform specific functions which are called at
init, exit, suspend and resume conditions. Till now these functions were
present in a platform driver with a fixme notes.
Similar functions modifying same set of registers will also be needed in
case of PCIe phy init/exit.
So move all these SATA platform code to phy-miphy40lp driver.
