Subject: drm/stm: dsi: move lane capability detection in probe()
Git-commit: 22f99f2db44771cf9569fc2e8c547ad3153d9384
Patch-mainline: v5.18-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
There is no need to re-compute the dsi lane capability because it
only depends on dsi hw version.
Since dsi hw version is detected at probe(), move there also the
assignment of dsi lane capability.
