This serials patches add mipi dsi support for rk3399. Except the basic mipi driver, we need also enable pmic rk808 for lcd power and enable i2c for rk808 communication. what's more, the needed clk and pwm for backlight is init in spl stage, make sure spl work first.

To enable mipi display, we need to enable pmic rk808 first for lcd3v3 power,which use i2c0 to communicate with soc. So enable i2c0.
