Subject: [PATCH] regulator: mt6397: convert to arch_initcall

Due to some device may need reulator operation in earlier boot time like gpu module which
power domain need regulator power on first. Move regulator of mt6397
initialization earlier in boot so that real devices can use regulator
without probe deferring.
