Subject: [PATCH v2 1/4] nvmem: rockchip-efuse: Change initcall to subsys

From: Finley Xiao <finley.xiao@...k-chips.com>

We will register a cpufreq notifier for adjusting opp's voltage, and it
need to fetch cpu's leakage from efuse in the notifier_call. so the efuse
driver should probe before cpufreq driver.
