This patch fixes the Meson8b USB1 dts node, changing the IRQ type
from edge rising to level high.
This avoids errors like "usb 1-1-port1: cannot reset (err = -110)" on
Odroid-C1+ board.
The patch also improves the same node adding the description of the digital
and analog regulators found in DWC2 USB controller.
