Subject: [PATCH] dma-contiguous: define proper name for global cma region

The current global cma region name defined as "reserved"
which is misleading, creates confusion and too generic.

Also, the default cma allocation happens from global cma region,
so, if one has to figure out all allocations happening from
global cma region, this seems easier.

Thus, change the name from "reserved" to "global-cma-region".
