i2c: imx: fix clock and pinctrl state inconsistency in runtime PM

In the Linux kernel, the following vulnerability has been resolved:

i2c: imx: fix clock and pinctrl state inconsistency in runtime PM

In i2c_imx_runtime_suspend(), the clock is disabled before switching

the pinctrl state to sleep. If pinctrl_pm_select_sleep_state() fails,

the runtime suspend is aborted but the clock remains disabled, causing

a system crash when the hardware is subsequently accessed.

Fix this by switching the pinctrl state before disabling the clock so

that a pinctrl failure leaves the clock enabled and the hardware

accessible.

In i2c_imx_runtime_resume(), restore the pinctrl state back to sleep

if clk_enable() fails to keep the consistent.
