[PATCH] Input: axp20x-pek - add AXP313a support

The AXP313a MFD driver registers its power button cell as "axp313a-pek",
but the axp20x-pek platform id table only matches "axp20x-pek" and
"axp221-pek". The power button therefore never probes on boards using the
AXP313a PMIC (e.g. the OrangePi Zero 2W).

Add the missing id table entry. The register layout used by the driver
matches the AXP313a, so the generic axp20x_info is reused.

Tested on: OrangePi Zero 2W (Allwinner H618 + AXP313a), kernel 7.1.13.
