Subject: [PATCH] drm/bridge: ite-it6505: add missing Kconfig option select

The IT6505 is using functions provided by the DRM_DP_HELPER driver.
In order to avoid having the bridge enabled but the helper disabled,
let's add a select in order to be sure that the DP helper functions are
always available.
