Subject: [PATCH AUTOSEL 6.8 03/24] usb: typec: ucsi_glink: rework quirks implementation

From: Dmitry Baryshkov <dmitry.baryshkov@...aro.org>

[ Upstream commit 3f81cf54c1889eeecbb8d9188f5f2f597622170e ]

In preparation to adding more quirks, extract quirks to the static
variables and reference them through match->data. Otherwise adding
more quirks will add the table really cumbersome.
