Allwinner R329 SoC has two pin controllers similar to ones on
previous
SoCs, one in CPUX power domain and another in CPUS.

This patch adds support for the CPUX domain pin controller.

No use of these.

Missed headers:
mod_devicetable.h

Thanks for these.

In addition, how to decide what header should be included? The code
