mfd: axp20x: Add support for AXP323

The X-Powers AXP323 is a very close sibling of the AXP313A. The only
difference seems to be the ability to dual-phase the first two DC/DC
converter, which adds another register.

Add the required boilerplate to introduce a new PMIC to the AXP MFD
driver. Where possible, this just maps into the existing structs defined
for the AXP313A, only deviating where needed.
