usb: typec: ucsi: yoga-c630: add DRM dependency

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

Add a dependency to force UCSI_LENOVO_YOGA_C630 to be a loadable module as
well in this configuration.
