[PATCH 1/2] ARM: imx_v6_v7_defconfig: Select CONFIG_USB_ONBOARD_HUB

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

The imx6qdl-udoo board has a USB2514 Hub connected to the
USB Host1 port.

Select CONFIG_USB_ONBOARD_HUB so that USB hub can be functional.

[PATCH 2/2] ARM: dts: imx6qdl-udoo: Enable USB host

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

Commit 8f2ca252ee1f ("ARM: dts: imx6qdl-udoo: Disable USB host to
work around boot issues") disabled USB host to avoid boot hang.

Properly describe the USB2514 USB hub to fix this issue.

Tested on a imx6q-udoo board and verified that it boots fine
and USB host functionality works.
