arm64: dts: qcom: x1e80100-crd: describe 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 1-0015: 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 VREG_MISC_3P3 is also used for things like the fingerprint
reader which are not yet fully described so mark the regulator as always
on for now.
