clk: imx: vf610: Disable automatic clock gating for lpuart in LPSTOP mode
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.
