sparc: Size mondo queues more sanely.

[ Upstream commit 961f65fc41cdc1f9099a6075258816c0db98e390 ]

There is currently no upper limit on the mondo queue sizes we'll use,
which guarentees that we'll eventually his page allocation limits, and
thus allocation failures, due to MAX_ORDER.

Cap the sizes sanely, current limits are:

CPU  MONDO	2 * max_possible_cpus
DEV  MONDO	256 (basically NR_IRQS)
RES  MONDO	128
NRES MONDO	4
