tty: serial: fsl_lpuart: support suspend/resume
In order to allow wake support in STOP sleep mode, clocks are
needed. Use imx_clk_gate2_cgr to disable automatic clock gating
in low power mode STOP. This allows to enable wake by UART using:
echo enabled > /sys/class/tty/ttyLP0/power/wakeup
However, if wake is not enabled, the driver should disable the
clocks explicitly to save power.
