[U-Boot] [PATCH v2 6/6] sunxi: axp: Remove non driver-model support from the axp gpio code

Now that all sunxi boards are using driver-model for gpio (*), we can remove
the non driver-model support from the axp gpio code, and the glue to call
into the axp gpio code from the sunxi_gpio non driver-model code.
*) For the regular u-boot build, SPL still uses non driver-model gpio for
now, but the SPL never uses axp gpios support and we were already not building
axp-gpio support for the SPL.
