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.

Move the axp-gpio code out of the drivers/power/axp*.c code, and into
a new separate axpi-gpio driver.
This change drops supports for the gpio3 pin on the axp209, as that requires
special handling, and no boards are using it.
Besides cleaning things up by moving the code to a separate driver, as
a bonus this change also adds support for the (non vusb) gpio pins on the
axp221 and the gpio pins on the axp152.
The new axp-gpio driver gets its own Kconfig option, and is only enabled
on boards which need it. Besides that it only gets enabled in the regular
u-boot build and not for the SPL as we never need it in the SPL.

Sunxi platforms come with at least 3 TWI (I2C) controllers and some platforms
even have up to 5. This adds support for every controller on each supported

Sunxi platforms have different possible mmc pin mux setups (except for mmc0),
which are different across platforms.
This lets users configure which is used through the CONFIG_MMC*_PINS Kconfig
options. This is especially relevant when a second (in addition to mmc0) port
is used and CONFIG_MMC_SUNXI_SLOT_EXTRA is enabled.

Each hardware feature exposed through the GPIO pin mux is usually using the same
function index (for a given port), so there is no need to define one value per
pin: one value per hardware feature per port is sufficient, avoids duplication
and makes everything easier to understand.

Some boards use GPIO-s on the pmic, one example of this is the A13-OLinuXino
board, which uses gpio0 of the axp209 for the lcd-power signal.
This commit adds support for gpio pins on the AXP209 pmic, the sunxi_gpio.c
changes are universal, adding gpio support for the other AXP pmics (when
necessary) should be a matter of adding the necessary axp_gpio_foo functions
to their resp. drivers, and add "#define AXP_GPIO" to their header file.
Note this commit only adds support for the non device-model version of the
gpio code, patches for adding support to the device-model version are very
welcome.
The string representation for these gpio-s is AXP0-#, the 0 in the AXP0 prefix
is there in case we need to support gpio-s on more then 1 pmic in the future.
At least A80 boards have 2 pmics, and we may end up needing to support gpio-s
on both.

bytes each time, this driver will only see very little use and thus is
limited to single byte transmission only.

as some devices do actually use mmc1 routed through PG, so change the routing
