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.

Please send clock driver changes in a separate patch.

How about splitting this patchset to two? few patches are having minor
fixes and the few patches might need some review and discussions.
May be some thing like DMA fixes and the other minor fixes.
