[U-Boot] [PATCH v4 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
SCSI_AHCI and is based on AHCI.

Changes in v4:
- Base on the latest mainline git version
- Let AHCI_MVEBU depend on AHCI and select SCSI_AHCI
ahci_mvebu driver is based on AHCI UCLASS, so let AHCI_MVEBU based on
AHCI; and this driver uses ahci_init() in ahci.c, so let it select
SCSI_AHCI. In this patch, DM_SCSI is not selected and it will be
selected in the later patch which adds scsi support by creating a SCSI
device as a child of mvebu ahci device.

Changes in v3:
- Use the new SPDX tags

Changes in v2:
- Add MAINTAINERS updating
