MLK-10957 : ARM: imx: gpc: do not turn off PU in GPC probe
There is narrow window that PRE driver is ready but GPU driver probe later,
and the later GPU driver turn on PU may cause 'PRE hang' issue. To simplify
thing, do not turn off PU in u-boot and PU power domain register.
check more information from below commit:
