mali_cm: Move ASV application to the init stage
Previous to [asv: Change initcall level to an earlier stage] the ASV voltages
would be applied too late for them being read out on ramfs post-init, or to
be changed at boot by scripts without being overridden by the ASV application
shortly after.

Since now we are guaranteed an initialized exynos_result_of_asv, do the ASV
application immediately on init, instead of DVFS runtime, to avoid the issue.
