The CHRG_CTRL1 and CHRG_CTRL2 registers are made for controlling
different battery charging settings such as the constant current charge
value.

The AXP22X also have a third register CHRG_CTRL3 which has settings for
battery charging too.

This adds the CHRG_CTRL1, CHRG_CTRL2 and CHRG_CTRL3 registers to the
list of writeable registers for AXP20X and AXP22X PMICs.

v2:
 - added AXP20X_CHRG_CTRL2 and AXP20X_CHRG_CTRL3 to the writeable
 registers table,
 - removed added reg range for ADC data in volatile regs range,
