[PATCH] i2c-rk3x: move setup to the earlier subsys initcall

From: Chris Zhong
Date: Mon Sep 22 2014 - 03:24:52 EST


Some device using this bus, such as regulators, they should register
as early as possible, so the I2C bus master needs to be loaded early.
Therefore initialize via subsys_initcall() is better.
