Enable regulator for usbdrd3_0 and usbdrd3_1.
Looking at the schematic pin diagram for MAX77802
USB3_0 and USB3_1 is regulated by LDO9 and LD011.

Fix the boot message of failed.

Thanks, applied with minor adjustments in commit message (joined first
three sentences into one paragraph, changed description of dmesg).

I'll send later to Kukjin for 4.3 (unless he picks it also).

Best regards,
Krzysztof
