snow: MP1.2 platfrom version is MPx16

Previously all MP variants of snow returned MP, but
there are scenarios where we want to tell apart
types of MP. Specifically MP1.2 changes from x8 to x16
memory and other userspace applications can now use
mosys platform version to query the board type.

TEST=run mosys platform version on x16 and x8 board
and verify x16 reports MPx16 and x8 board shows MP
