video: fbdev: pxa3xx_gcu: fix error return code in pxa3xx_gcu_probe()
platform_get_irq() returns an error code, but the pxa3xx_gcu driver
ignores it and always returns -ENODEV. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.
Also, notice that platform_get_irq() no longer returns 0 on error:

Print and propagate the return value of platform_get_irq on failure.
This issue was detected with the help of Coccinelle.
