drm/loongson: Error out if no VRAM detected
When a Loongson laptop is equipped with a Radeon GPU, it can be true that
there is no dedicated VRAM soldered on the motherboard. This is probably
for cost reason, but drm/loongson driver is probed because the platform
BIOS (either UEFI or PMON) forget to disable the integrated GPU.
So in the lsdc_get_dedicated_vram() function, we error out if no dedicated
VRAM detected. This fix nothing, but serve as a sanity check only.
