dm: gpio: Refactor to prepare for live tree support

Move the main part of the GPIO request function into a separate function
so that it can be used by the live tree function when added. Update the
xlate method to use a node reference.

Update all GPIO drivers to handle the modified xlate() method.

dm: Rename dev_addr..() functions

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

sunxi: gpio: Add support for the gpio banks which are part of the R-io cluster

sun6i and later have a couple of io-blocks which are shared between the
main CPU core and the "R" cpu which is small embedded cpu which can be
active while the main system is suspended.

These gpio banks sit at a different mmio address then the normal banks,
and have a separate devicetree node and compatible, this adds support for
these banks to the sunxi-gpio code when built with device-model support.

sunxi: axp: Move axp gpio code to a separate axpi-gpio driver

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.
