VBUS drive is supported on AXP221 and later PMICs. Rework the macros
so we can support this on later PMICs without too much work.Signed-off-by: Chen-Yu Tsai

Stop prefixing the axp functions for setting voltages, etc. with the
model number, there ever is only one pmic driver built into u-boot,
this allows simplifying the callers.Signed-off-by: Hans de Goede

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.Signed-off-by: Hans de Goede

Move the register helpers used to access the registers via p2wi resp.
rsb bus on the otherwise identical axp221 and axp223 pmics to a separate
file, so that they can be used by the upcoming standalone axp gpio driver
too.Signed-off-by: Hans de Goede

Change the axp_gpio_foo function prototypes to match the gpio uclass op
prototypes, this is a preparation patch for moving the axp gpio code to
a separate driver-model gpio driver.Note that the ugly calls with a NULL udev pointer in drivers/gpio/sunxi_gpio.c
this adds are removed in a later patch.Signed-off-by: Hans de Goede

This converts the VBUS detection and enable logic to GPIO instead of separate
axp functions and checks that have to be used aside usual GPIO functions.Signed-off-by: Paul Kocialkowski

Some of the AXP PMICs support VBUS detection, i.e. checking whether
VBUS power input is available and usable (supplied by an external
source). A few boards use this instead of a separate GPIO to detect
VBUS on USB OTG.Signed-off-by: Chen-Yu Tsai

And also add Kconfig option for selecting ELDO3 voltage. The reason
for having this option is that the Android kernel sets ELDO3 to
1.2V when powering up LCD in the case if 'lcd_if' configuration
variable is set to 6 (LCD_IF_EXT_DSI) in the FEX file. Most likely
to supply power for a SSD2828 chip.However on the MSI Primo81 tablet, which is using this particular
'lcd_if = 6' setup for LCD, setting the ELDO3 voltage appears to
be unnecessary and it works regardless. Having no schematics of
this tablet, I can only guess that 1.2V is supplied to SSD2828
in some other way.Signed-off-by: Siarhei Siamashka

The axp221 / axp223's N_VBUSEN pin can be configured as an output rather
then an input, add axp_drivebus_enable() and _disable() functions to set

The axp223 appears to be the same as the axp221, except that it uses the
