Miaoqian Lin 6a0cceb1a8 drm/pl111: Fix error handling in pl111_amba_probe 
commit 0ddd3bb4b1 upstream.

Jump to the existing dev_put label when devm_request_irq() fails
so drm_dev_put() and of_reserved_mem_device_release() run
instead of returning early and leaking resources.

Found via static analysis and code review.

Fixes: bed41005e6 ("drm/pl111: Initial drm/kms driver for pl111")
