Series of: reserved_mem: Introduce devres helpers and convert drivers |

Commit Message

Mukesh Ojha July 3, 2026, 7:38 p.m. UTC 
Switch to devm_of_reserved_mem_device_init() so the reserved memory
region is released automatically on probe failure or device unbind.
Remove the three explicit of_reserved_mem_device_release() calls in
the setup_fail error path, the bind error path, and hdlcd_drm_unbind().
