sata_highbank: fix deferred probing

Browse source

[ Upstream commit 4a24efa16e ]

The driver overrides the error codes returned by platform_get_irq() to
-EINVAL, so if it returns -EPROBE_DEFER, the driver would fail the probe
permanently instead of the deferred probing. Switch to propagating the
error code upstream, still checking/overriding IRQ0 as libata regards it
as "no IRQ" (thus polling) anyway...

Fixes: 9ec36cafe4 ("of/irq: do irq resolution in platform_get_irq")
