ata: sata_mv: Use platform_get_irq() to get interrupt

Extract platform_get_irq() out of the conditional block to run it
unconditionally, replacing the direct use of irq_of_parse_and_map()
for DT-based systems. This simplifies the probe logic and avoids the
need for irq_dispose_mapping.

Remove dead branch for platform_get_irq(). It intercepts 0 and returns
-EINVAL, which goes to the first one.
