Have you noticed that it is already the case in mainline? My colleague
Maxime Ripard (Cc'ed) is the maintainer of the mainline Allwinner sunxi
effort. It already supports a number of boards, has a pinctrl driver, a
GPIO driver, serial port is working, network is working, I2C is

All in mainline, completely Device Tree based.

So isn't this entire discussion completely moot? The mainline support
for sunxi has already started since 6 months or so, and has been Device
Tree based from day one.
