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).
