PM / devfreq: rk3399_dmc: fix error return code in rk3399_dmcfreq_probe()
platform_get_irq() returns an error code, but the rk3399_dmc
driver ignores it and always returns -EINVAL. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly.
Notice that platform_get_irq() no longer returns 0 on error:

Print and propagate the return value of platform_get_irq on failure.
