Allwinner A64 has a I2C controller, which is in the R_ MMIO zone and has two groups of pinmuxes on PL bank, so it's called R_I2C.
Add support for this I2C controller and the pinmux which doesn't conflict with RSB

These changes are in the Linux DT, so we'd be better off syncing that DT, instead of adding just those two nodes.
Thanks! Maxime
