Ken Ma 592b4a7e97 ata: mvebu: move mvebu sata driver to drivers/ata directory
Currently mvebu sata driver is in arch/arm/mach_mvebu directory, this
patch moves it to drivers/ata directory with renaming "sata.c" to
"ahci_mvebu.c" which is aligned to Linux.
New ahci driver's kconfig option is added as AHCI_MVEBU which selects
SCSI_AHCI and is based on AHCI.
