Allwinner DT changes for 4.21

This is a quite big pull request this time, with a huge number of changes
(and patches) due to us fixing the vast majority of the DTC warnings our DT
had.

We also have a bunch of other good, more meaningful, changes:
  - Support for the new Allwinner T3 (rebranded R40) and f1c100s (armv5)
    SoCs
  - AXP803 PMIC AC Power supply support
  - Rework of the oscillators tree
  - Two new boards: the t3-cqa3t-bv3 and Lichee Pi Nano

Plus a few enhancements here and there.
