MLK-11281-10 ARM: imx: add ccm save/restore for lpsr When exit from LPSR mode, CCM settings will be lost, so we need to do CCM state retention support to make sure after resume from LPSR mode, clk tree settings are same as before entering LPSR; Due to hardware design requirement, CCM clk root registers access needs their parents enabled, so we use special sequence to restore PLLs, PFDs, ROOTs, and LPCGs.
