[PATCH -next] drm/fsl-dcu: Remove unnecessary print function dev_err()

[Yang Li]

The print function dev_err() is redundant because platform_get_irq()
already prints an error.

Eliminate the follow coccicheck warning:
./drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c:277:2-9: line 277 is
redundant because platform_get_irq() already prints an error
