ata: fix Marvell SATA driver dependencies

Make sata_mv host driver depend on PCI || ARCH_DOVE || ARCH_KIRKWOOD || ARCH_MV78XX0 || ARCH_MVEBU || ARCH_ORION5X config options as Marvell SATA support covers both Marvell PCI devices and Marvell Dove, Kirkwood, MV78xx0, Armada 370/XP and Orion5x SoCs (for non-PCI devices the driver to work requires suitable device tree node or platform device to be defined). Additionally allow the driver build if COMPILE_TEST config option is set.

---
v4:
- updated patch description
v3:
- added dependencies for Marvel Dove and MV78xx0
v2:
- resynced patch with libata/for-3.15 branch (previous patch was against libata/for-next branch and SATA_MV selects GENERIC_PHY in that branch)
