Subject: [PATCH -next] drm: Remove unnecessary print function dev_err()

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

Eliminate the follow coccicheck warning:
./drivers/gpu/drm/sprd/sprd_dpu.c:808:2-9: line 808 is redundant because platform_get_irq() already prints an error
