msdk: bufferpool: refactor memory type decision

Browse source 
The memory type was used as bitwise enum, but the enum was not
defined in that way.

Nonetheless, most of the usage of the memory type was as mutually
exclusive options, rather than option composition.

This patch refactor how the memory type is defined, so it is kept
the mutual exclusion among options.
