ALSA: Add support of AudioScience ASI boards

Added the support of AudioScience ASI boards.
The driver has been tested for years on alsa-driver external tree,
now finally got merged to the kernel.

Functions for reading DSP code to load into DSP
hpi_dspcode_defines HPI DSP code loading method
Define exactly one of these to select how the DSP code is supplied to
the adapter.
End users writing applications that use the HPI interface do not have to
use any of the below defines; they are only necessary for building drivers
HPI_DSPCODE_FILE:
DSP code is supplied as a file that is opened and read from by the driver.
HPI_DSPCODE_FIRMWARE:
DSP code is read using the hotplug firmware loader module.
Only valid when compiling the HPI kernel driver under Linux.
