The MT7628A is the successor to the MT7620 and pin compatible with the
MT7688A, although the latter supports only a 1T1R antenna rather than
a 2T2R antenna.
This commit adds support for the following features:
- UART
- USB PHY
- EHCI
- Interrupt controller
- System controller
- Memory controller
- Reset controller

Ralf: I've added this patch to both my vocore2 and omega2+
patchsets for ease of review, please only merge it once :-)
Changes in V2:
- Add MT7628 to patchset to keep kbuild happy and retain context
- Rename multiple DT nodes to standard names
- Add labels for uarts
- Rename USB PHY handle

The VoCore2 board is a low cost MT7628A based board with 128MB RAM, 16MB
flash and multiple external peripherals.
This initial DTS provides enough support to get to userland and use the USB
port.
