Subject: drm/i915/display: add intel_fdi_link_train wrapper.
Git-commit: 4360a2b54fd7e6c7ff66869b2fbb55cac7a9c325
Patch-mainline: v5.16-rc1
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
This wraps the fdi link training vfunc to make it clearer.
