Subject[PATCH v1 2/4] gpio: dwapb: Read GPIO base from gpio-base property
Date
For backward compatibility with some legacy devices introduce
a new (*) property gpio-base to read GPIO base. This will allow
further cleanup of the driver.

*) Note, it's not new for GPIO library since mockup driver is
using it already.
