drm/mediatek: mtk_dsi: 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/mediatek/mtk_dsi.c:1092:2-9: line 1092 is redundant
because platform_get_irq() already prints an error
