commit d14cd998e67ba8f1cca52a260a1ce1a60954fd8b upstream.
Selecting DRM_AUX_HPD_BRIDGE is not possible from a built-in driver when CONFIG_DRM=m:
WARNING: unmet direct dependencies detected for DRM_AUX_HPD_BRIDGE Depends on [m]: HAS_IOMEM [=y] && DRM [=m] && DRM_BRIDGE [=y] && OF [=y] Selected by [y]: - UCSI_HUAWEI_GAOKUN [=y] && USB_SUPPORT [=y] && TYPEC [=y] && TYPEC_UCSI [=y] && EC_HUAWEI_GAOKUN [=y] && DRM_BRIDGE [=y] && OF [=y]
Add the same dependency we have in similar drivers to work around this.
