[PATCH] arm64: dts: rockchip: vdd_log is not an i2c slave

[Vicente Bergas]

The vdd_log power supply is controlled by a PWM pin, not by i2c register access.
There is a boot message that reports an error about not being able to bring that supply up.
Also, the eMMC is not detected and /dev/mmcblk2 does not exist.
