[ALSA] Increase capture buffer sizes.

/*

 *  Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>

 *  Driver p16v chips

 *  Version: 0.22

 *  Version: 0.25

 *

 *  FEATURES currently supported:

 *    Output fixed at S32_LE, 2 channel to hw:0,0

 *    e.g. When HD Capture source is set to SPDIF,

 *    setting HD Capture channel to 0 captures from CDROM digital input.

 *    setting HD Capture channel to 1 captures from SPDIF in.

 *  0.25

 *    Include capture buffer sizes.

 *

 *  BUGS:

 *    Some stability problems when unloading the snd-p16v kernel module.
