[ALSA] Fix and clean-up of vxpocket driver 

Documentation,PCMCIA Kconfig,Digigram VX Pocket driver
- Fixed Oops with request_firmware()
- Detect the card type in runtime (vxpoocket v2 or 440)
- snd-vxp440 driver is merged to snd-vxpocket
- Clean up the code

Module snd-vxp440
-----------------
Module for Digigram VX-Pocket 440 PCMCIA card.
ibl - Capture IBL size. (default = 0, minimum size)
Module supports up to 8 cards. The module is compiled only when
PCMCIA is supported on kernel.
To activate the driver via the card manager, you'll need to set
up /etc/pcmcia/vxp440.conf. See the sound/pcmcia/vx/vxp440.c.
When the driver is compiled as a module and the hotplug firmware
is supported, the firmware data is loaded via hotplug automatically.
Install the necessary firmware files in alsa-firmware package.
When no hotplug fw loader is available, you need to load the
firmware via vxloader utility in alsa-tools package.
About capture IBL, see the description of snd-vx222 module.
Note: the driver is build only when CONFIG_ISA is set.
Module snd-ymfpci
