samd: parameterize memory and flash sizes 

Various SAMD devices have different amounts of memory. Up until now, all
SAMD devices have had the same amount, and therefore this value was
hardcoded to 32k of RAM and 256k of flash.

Add a parameter to the description field and set it to default to the
previous values. Use this description field when adding memories to the
target definition.
