power: supply: mt6360_charger: Fix of_match for usb-otg-vbus regulator

The of_match shall correspond to the name of the regulator subnode,
or the deprecated `regulator-compatible` property must be used:
failing to do so, the regulator won't probe (and the driver will
as well not probe).

Since the devicetree binding for this driver is actually correct
and wants DTs to use the "usb-otg-vbus-regulator" subnode name,
fix this driver by aligning the `of_match` string to what the DT
binding wants.
