So far every Allwinner SoC used the same basic pincontroller/GPIO register frame, and just differed by the number of implemented banks and pins, plus some special functionality from time to time. However the D1 and successors use a slightly different pinctrl register layout. Use that opportunity to drop "struct sunxi_gpio", that described that MMIO frame in a C struct. That approach is somewhat frowned upon in the Linux world and rarely used there, though still popular with U-Boot. Switching from a C struct to a "base address plus offset" approach allows to switch between the two models more dynamically, without reverting to preprocessor macros and #ifdef's. Model the pinctrl MMIO register frame in the usual "base address + offset" way, and replace a hard-to-parse CPP macro with a more readable static function. All the users get converted over. There are no functional changes at this point, it just prepares the stages for the D1 and friends.
