ODROID C2: Fix usb/dwc_otg

[wrxtasy]

Problems with C2 USB HID attached devices are shown as errors in the Kernel log:

Solution was to pull in some Hardkernel commits to fix USB Hub HID issues.

On the C2 this also allows BT USB HID devices like the Xiaomi Mi Box remote (with further LE patching) and the PS3 USB connected controllers to work properly.

The Lakka guys will likely be interested in USB controllers working.

Also required as a Kernel Config:

Tested only on the C2, further testing required on the WeTek Hub / Play2

meh on wetek play 2

without adjusting gxbb_p200_2G_wetek_play_2.dts - usb hid connected to side usb port not recognised
with adjusted gxbb_p200_2G_wetek_play_2.dts: http://sprunge.us/OLXb

Thx.
It may just be easier to throw the C2 specific Linux patches in their own LE C2 project folder otherwise headaches are likely going forward.

Thank you @wrxtasy for submitting this PR. I will do some tests the next few days. I'd like to not use a project specific patch for C2 only. Especially with all those Retroplayer changes coming in LE9/Kodi 18 people are gonna want their controllers to work on WP2 too.

EDIT: I just understood that it's just a C2 issue. Sorry for the confusion. A project specific patch might be a solution too.

Dumped the problematic Hardkernel dwc_otg revert.

Tested on C2 and WeTek Hub with:

USB HID - Sony PLAYSTATION(R)3 Controller and
C2 - USB BT - HID Xiaomi Mi Box remote

and no regressions this time with the Hub.
Will submit a further LE PR for correct UHID Kernel configs

Quick test shows no more issues on WP2. I'll put it in my builds today and see if there are any issues reported.

Good news.
Will have to look into some Kodi Retro gaming next - now my old PS3 controllers work ! 👍
