Subject[PATCH] drm: aspeed: Select CMA only if available
Date
When building this driver for architectures where CMA is not available.

Fixes: 4f2a8f5898ec ("drm: Add ASPEED GFX driver")
Reported-by: Stephen Rothwell <sfr@canb.auug.org.au>
Reported-by: kernel test robot <lkp@intel.com>
Signed-off-by: Joel Stanley <joel@jms.id.au>
---
This fixes the build break.

Another question is if we need to select this at all, as we have a
reserved memory region to allocate from. I am not familiar with this
area, so advice is welcome.
