[U-Boot] [PATCH 1/4] ata: mvebu: move mvebu sata driver to drivers/ata directory

[make at marvell.com]

From: Ken Ma <make at marvell.com>

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
DM_SCSI.
