Series Enable Multi Core Timer (MCT) for gs101 | expand

Update cmu_misc so it is registered early, as it contains
the gate which clocks the Multi Core Timer (MCT). This clock
is required early in boot, otherwise exynos_mct will fail
obtaining the clock.

Note this wasn't previously an issue as exynos_mct wasn't
enabled.
