[PATCH v2] arm64: dts: x1e80100-crd: describe HID supplies

[Johan Hovold]

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.

Changes in v2:
 - amend the pin config in order not to rely on the boot firmware

Sure, will switch these to match the new style that this driver mostly
follows (but as we've discussed before, the traditional style that most
dt still use for pinctrl is what I used above).
