Subject: [PATCH -next] media: platform: 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 warnings:
./drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_drv.c:119:2-9:
line 119 is redundant because platform_get_irq() already prints an error
./drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_hw.c:103:2-9:
line 103 is redundant because platform_get_irq() already prints an error
