MLK-20528-2 imx8: Enable clocks LPCG
To support partition reboot, the u-boot has to enable clocks by LPCG.
The LPCG will reset to default value only when the subsystem is totally
power off and reset. However, the resources in one subsystem may belong
to different partitions, so the partition reboot may not reboot the entire
subsystem.
Powers, clocks/lpcg, GPR, IP may not reset depends on various cases and
HW design. Thus, AP software has to ensure everything is reset by SW
itself to support such above cases.
