drm/mediatek: set DMA max segment size

[ Upstream commit 070955558e820b9a89c570b91b1f21762f62b288 ]

This driver requires imported PRIME buffers to appear contiguously in
its IO address space. Make sure this is the case by setting the maximum
DMA segment size to a more suitable value than the default 64KB.
