Subject: [PATCH v6 01/17] dt-bindings: mfd: axp20x: Add AXP305 compatible (plus optional IRQ)

The AXP305 PMIC used in AXP805 seems to be fully compatible to the
AXP805 PMIC, so add the proper chain of compatible strings.

Also at least on one board (Orangepi Zero2) there is no interrupt line
connected to the CPU, so make the "interrupts" property optional.
