arm64: dts: qcom: x1e78100-t14s: fix missing HID supplies

Add the missing HID supplies to avoid relying on other consumers to keep
them on.

This also avoids the following warnings on boot:

	i2c_hid_of 0-0010: supply vdd not found, using dummy regulator
	i2c_hid_of 0-0010: supply vddl not found, using dummy regulator
	i2c_hid_of 1-0015: supply vdd not found, using dummy regulator
	i2c_hid_of 1-002c: supply vdd not found, using dummy regulator
	i2c_hid_of 1-0015: supply vddl not found, using dummy regulator
	i2c_hid_of 1-002c: supply vddl not found, using dummy regulator
	i2c_hid_of 1-003a: supply vdd not found, using dummy regulator
	i2c_hid_of 1-003a: supply vddl not found, using dummy regulator

Note that VCC3B is also used for things like the modem which are not yet
described so mark the regulator as always-on for now.
