Add support for calculating CMA usage from kernel drivers

The kernel exposes how much memory drivers have allocated from
CMA regions through sysfs. This information can be treated as
memory that is in use by the kernel, and therefore not part of
lost RAM.

So, add support for calculating how much memory kernel drivers
have allocated from the system's CMA regions.
