ata: sata_mv: accept 1 or 2 resources in platform probe

Browse Source 
Board files in arch/arm/plat-orion, arch/arm/mach-dove,
arch/arm/mach-mv78xx0 and arch/arm/mach-orion5x still register the
"sata_mv" device with two resources (IORESOURCE_MEM plus IORESOURCE_IRQ).
Those devices are rejected with -EINVAL, so SATA no longer probes on
legacy Marvell Orion/Kirkwood-style boards.

Accept both 1 resource (DT, IRQ fetched via platform_get_irq()) and 2
resources (legacy, IRQ supplied as a second resource) so both probing
paths work.

Fixes: b3b2bec964 ("ata: sata_mv: Fixes expected number of resources now IRQs are gone")
