[PATCH v2 3/11] drm: pl111: Use devm_of_reserved_mem_device_init()

[Mukesh Ojha]

Switch to devm_of_reserved_mem_device_init() so the reserved memory
region is released automatically on probe failure or device removal.
Remove the explicit of_reserved_mem_device_release() calls in the
dev_put error path and pl111_amba_remove().
