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.

Fixes: 88d8f3ac9c67 ("usb: typec: add support for the nb7vpq904m Type-C Linear Redriver")
