Subject: drm/bridge: ite-it6505: add missing Kconfig option select
Git-commit: 841e512ffb64898db6322c0619f6bbc41266d86f
Patch-mainline: v5.18-rc6
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

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.
