nvmem: rockchip-efuse: Change initcall to subsys

We will add a avs driver to adjust opp's voltage according to leakage.
As it need register a notifier before cpufreq starts, and make cpufreq
defer probe is probably not really easy, so avs should probe earlier
than cpufreq, efuse should probe earlier than avs.
