Subject: [PATCH v8 8/8] ARM: dts: imx6q-evi: Fix onboard hub reset line
From: Joshua Clayton <stillcompiling@...il.com>
Previously the onboard hub was made to work by treating its
reset gpio as a regulator enable.
Get rid of that kludge now that pwseq has added reset gpio support
Move pin muxing the hub reset pin into the usbh1 group
