[PATCH v2 00/12] sunxi: Migrate to DM_I2C

[Samuel Holland]

This series does the initial work to migrate sunxi boards to DM_I2C.
Version 1 of this series bitrotted quite a bit, so there is some
reorganization in version 2.

First it takes care of the PMIC:
 - Patches 1-2 clean up the PMIC Kconfig, though they are not strictly
   necessary after 7abf178b, and are independent from the other patches.
 - Patch 3 then adds a DM_PMIC driver.
 - Patches 4-6 prepare to move the P2WI/RSB bus drivers to drivers/i2c.
 - Patches 7-8 move and add DM_I2C versions of those two drivers.
 - Patches 9-10 migrate the "pmic_bus" functions to use the DM_I2C bus
   and DM_PMIC driver when possible.
Then it takes care of the LCD panels:
 - Patch 11 converts those drivers to use DM_I2C.
Finally, patch 12 switches all sunxi boards over to DM_I2C.

I have build-tested each commit on all sunxi boards.

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.

Changes in v2:
- Rebase to pick up 7abf178b ("power: Tidy up #undef of CONFIG_DM_PMIC")
- Rebase to pick up 7abf178b ("power: Tidy up #undef of CONFIG_DM_PMIC")
- Replace axp_pmic_bind() with `.bind = dm_scan_fdt_dev`
- New patch to account for I2C Kconfig changes
- Renamed Kconfig symbol to SYS_I2C_SUN6I_P2WI
- Moved entire P2WI driver source to drivers/i2c
- Renamed Kconfig symbol to SYS_I2C_SUN8I_RSB
- Moved entire RSB driver source to drivers/i2c
- Update IS_ENABLEDs in pmic_bus.c to match chages to previous patches
