Icenowy Zheng May 27, 2017, 10:23 a.m. UTC 
As A20 is designed as a pin-compatible upgrade of A10, their pin
controller are very similar, and can share one driver.

Add A20 support to the A10 driver.

Signed-off-by: Icenowy Zheng <icenowy@aosc.io>
---
Changes in v3:
- Enable A10 driver for A20 and disable A20 driver in this commit, in
  order to prevent A10 driver from conflicting with A20 driver.
