[PATCH AUTOSEL 6.11 10/15] usb: typec: ucsi: glink: be more precise on orientation-aware ports

[Sasha Levin <sashal@kernel.org>]

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

[ Upstream commit de9df030ccb5d3e31ee0c715d74cd77c619748f8 ]

Instead of checking if any of the USB-C ports have orientation GPIO and
thus is orientation-aware, check for the GPIO for the port being
registered. There are no boards that are affected by this change at this
moment, so the patch is not marked as a fix, but it might affect other
boards in future.
