spi: rockchip-sfc: fix platform_get_irq.cocci warning
Remove dev_err() messages after platform_get_irq*() failures.

spi: rockchip-sfc: Fix assigned but never used return error codes
Currently there are two places where the error return variable ret is
being assigned -ETIMEDOUT on timeout errors and this value is not
being returned. Fix this by returning -ETIMEDOUT rather than redundantly
assiging it to ret.
