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

From: Arnd Bergmann <[email protected]>

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]:

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

Fixes eb90d36bfa06 ("usb: typec: ucsi: yoga-c630: register DRM HPD bridge")
