[PATCH] spi/pl022: fix spi-pl022 pm enable at probe

[Linus Walleij]

From: Michel JAOUEN <michel.jaouen-0IS4wlFg1OjSUeElwK9/Pw@public.gmane.org>

amba drivers does not need to enable pm runtime at probe.
amba_probe already enables pm runtime.

This rids this warning in the ux500 boot log:
ssp-pl022 ssp0: Unbalanced pm_runtime_enable!
