[PATCH] irqchip: irq-imx-intmux: fix runtime PM cleanup

[Jiawen Liu]

Fix imx_intmux_probe lifecycle error path.

Probe enables runtime PM and clock. Failures after clock enable only
disable clock and leak PM runtime reference/enable. Clk cleanup is
incomplete because PM runtime state is left enabled/ref held on later
probe failures.

Balance runtime PM setup on imx-intmux probe failures in
imx_intmux_probe.
