[PATCH v2 3/6] media: nuvoton: npcm-video: Use devm_of_reserved_mem_device_init()

[Mukesh Ojha <mukesh.ojha@oss.qualcomm.com>]

Switch to devm_of_reserved_mem_device_init() so the reserved memory
region is released automatically on probe failure or device removal.
Remove the four explicit of_reserved_mem_device_release() calls and
collapse the now-empty err_release_mem label into err_free.
