[PATCH 00/11] sunxi: Migrate to DM_I2C

[Samuel Holland]

This series does the initial work to migrate sunxi boards to DM_I2C.

First it takes care of the PMIC:
 - Patches 1-2 add DM_I2C versions of two drivers.
 - Patches 3-4 allow us to use DM_PMIC without DM_SPL.
 - Patch 5 then adds a DM_PMIC driver.
 - Patches 6-9 migrate the "pmic_bus" functions to use that DM_PMIC
   driver when possible.
Then it takes care of the LCD panels:
 - Patch 10 converts those drivers to use DM_I2C.
Finally, patch 11 switches all sunxi boards over to DM_I2C.

There is some remaining work to clean up uses of pmic_bus in U-Boot
proper and replace them with DM_PMIC functions:
 - drivers/gpio/axp_gpio.c - I have a series for this.
 - do_poweroff() in drivers/gpio/axp???.c - I have a series for this.
 - axp_get_sid() in drivers/power/axp221.c - Not sure what to do here.
 - axp_set_eldo() in drivers/video/sunxi/sunxi_display.c - This will
   need a DM_REGULATOR driver.

I have build-tested each commit on all sunxi boards, and boot-tested
the series on Pine H64 (H6) and Orange Pi Zero2 (H616).
