[PATCH] ALSA: ctxfi: Bump playback substreams to 256

[Maarten Lankhorst <m.b.lankhorst@gmail.com>]

There are references in the code to 256 sources, so I tested it with 256 aplays,
of which the first and last with real data and the rest playing /dev/zero .

Also increase amount of page tables, so the default aplay size works.
