[PATCH AUTOSEL 5.15 1/2] power: supply: cros_usbpd: provide ID table for avoiding fallback match

[Sasha Levin]

From: Tzung-Bi Shih <tzungbi@xxxxxxxxxx>

[ Upstream commit 0f8678c34cbfdc63569a9b0ede1fe235ec6ec693 ]

Instead of using fallback driver name match, provide ID table[1] for the
primary match.
