gma: Configure cursor plane

Programming the cursor plane registers is straight forward.

On newer hardware, we also have to account for the cursor in GPU
internal buffer allocation. Fortunately, we have enough resources
for a static configuration that always accounts for a cursor.

Cursors with a location that is off limits are placed off-screen
in the top-left corner, hence, are invisible.
