[PATCH] drm/mediatek: select DRM_GEM_DMA_HELPER if DRM_FBDEV_EMULATION=y

[Chen-Yu Tsai]

With the recent switch from fbdev-generic to fbdev-dma, the driver now
requires the DRM GEM DMA helpers. This dependency is missing, and will
cause a link failure if fbdev emulation is enabled.

Add the missing dependency.
