[ Upstream commit 5831882880e9a1749553e78f9d8369fe33116aaf ]
Last 8 bit of _CFG started being used in later IdeaPads, thus 30th bit doesn't always show whether device supports touchpad or touchpad switch. Remove checking bit 30 of _CFG, so older IdeaPads like S10-3 can switch touchpad again via touchpad attribute.
This reverts commit b3ed1b7fe378 ("platform/x86: ideapad-laptop: check for touchpad support in _CFG").
