[PATCH 12/21] ath10k: Support up to 64 vdevs.

[greearb at candelatech.com]

From: Ben Greear <greearb at candelatech.com>

The (1 << x) - 1 trick won't work when you
are trying to fill up all 64 bits, so add special
case for that.

And, move the limits to the per-nic structure instead
of per-driver to allow better dynamic use of the limits.
