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.
