[PATCH v2] drm/tidss: oldi: convert to devm_drm_bridge_alloc() API

[Jayesh Choudhary]

DRM bridges now use "devm_drm_bridge_alloc()" for allocation and
initialization. "devm_kzalloc()" is not allowed anymore and it results
in WARNING. So convert it.

Changelog v1->v2:
- Fix typo in commit message
- Put the oldi parent and child node in case of error before returning
  (as pointed out by Aradhya in v1)
- Pick up "R-by" tags
