PATCH 1/1 usb: typec: ucsi: add DRM_BRIDGE dependencies

From: Arnd Bergmann <[email protected]>

Selecting CONFIG_DRM_AUX_HPD_BRIDGE is not allowed when its dependencies are not met:

WARNING: unmet direct dependencies detected for DRM_AUX_HPD_BRIDGE
Depends on [n]: HAS_IOMEM [=y] && DRM [=n] && DRM_BRIDGE [=n] && OF [=n]
Selected by [m]:
- UCSI_HUAWEI_GAOKUN [=m] && USB_SUPPORT [=y] && TYPEC [=y] && TYPEC_UCSI [=m] && EC_HUAWEI_GAOKUN [=m]

ERROR: modpost: "drm_bridge_hpd_notify" [drivers/gpu/drm/bridge/aux-hpd-bridge.ko] undefined!
ERROR: modpost: "devm_drm_bridge_add" [drivers/gpu/drm/bridge/aux-hpd-bridge.ko] undefined!

Add the same dependencies for the new UCSI_HUAWEI_GAOKUN driver to ensure it always builds cleanly.
