arm64: dts: qcom: sc7280-herobrine-villager: correct trackpad supply

The hid-over-i2c takes VDD, not VCC supply.  Fix copy-pasta from other
Herobrine boards which use elan,ekth3000 with valid VCC:

  sc7280-herobrine-villager-r1-lte.dtb: trackpad@2c: 'vcc-supply' does not match any of the regexes: 'pinctrl-[0-9]+'
