v2:
- replaced µ character by a common u for micro units to make checkpatch
happy,
- use of structure for specific data instead of an ID and if

- use dev_get_regmap instead of manually looking for it in the parent

This maps the IIO channels acin_i and acin_v (respectively exposing the
current current and voltage measures of the AC power supply) to the AC
power supply driver.
Only the AXP20X PMICs have these ADC channels and thus they are only
mapped for this version of the PMIC.

The X-Powers AXP20X and AXP22X PMICs have an AC entry to supply power to
the board. They have a few registers dedicated to the status of the AC
power supply.
This adds the DT binding documentation for the AC power supply for
AXP20X and AXP22X PMICs.

The registers 0x56 and 0x57 of AXP22X PMIC store the value of the
internal temperature of the PMIC.
This patch modifies the name of these registers from AXP22X_PMIC_ADC_H/L
to AXP22X_PMIC_TEMP_H/L so their purpose is clearer.
