usb: typec: nb7vpq904m: fix CONFIG_DRM dependency
With the following config set: CONFIG_DRM=m CONFIG_DRM_PANEL=y CONFIG_DRM_BRIDGE=y CONFIG_DRM_PANEL_BRIDGE=y CONFIG_TYPEC_MUX_NB7VPQ904M=y vmlinux fails on the following symbols: ld.lld: error: undefined symbol: devm_drm_bridge_add ld.lld: error: undefined symbol: devm_drm_of_get_bridge Add dependendy on DRM || DRM=no since CONFIG_DRM dependency is optional and guarded by: IS_ENABLED(CONFIG_OF) && IS_ENABLED(CONFIG_DRM_PANEL_BRIDGE) in the drive. Also add "select DRM_PANEL_BRIDGE if DRM" to clarify DRM_PANEL_BRIDGE is required if CONFIG_DRM is enabled.
