Samuel Holland a3a6dde671 gpio: axp: Select variant from compatible at runtime
There are three major variants of the AXP PMIC GPIO functionality (plus
PMICs with no GPIOs at all). Except for GPIO3 on the AXP209, which uses
a different register layout, it is straightforward to support all three
variants with a single driver. Do this, and in the process remove the
GPIO-related definitions from the PMIC-specific headers, and therefore
the dependency on AXP_PMIC_BUS.
