[PATCH 0/2] Add basic support for Mediatek MT2701 SoC

[erin.lo-NuS5LvNUpcJWk0Htik3J/w]

MT2701 is a SoC based on 32bit ARMv7 architecture. It contains 4 CA7 cores.
MT2701 share many HW IP with MT65xx series. This patchset was tested
on MT2701 evaluation board, and boot to shell ok.

This series contains document bindings, device tree including
interrupt, uart, timer and wdt.
