[PATCH 13/21] Remove redundant struct members.

[linux]

From: Eliot Blennerhassett <eblennerhassett@audioscience.com>

Structs hpi_adapter and snd_card_asihpi had members that
duplicate those in underlying hpi_adapter_obj or whose info
can be retrieved using hpi_adapter_get_info().

Print less info in probe function, it can be retrieved from /proc.

Avoid name redundancy: hpi_adapter_obj.adapter_type renamed to .type

[PATCH 18/21] Add HPI version to module description.

[linux]

From: Eliot Blennerhassett <eblennerhassett@audioscience.com>

It is useful to know the HPI version without having to load the module,
in order to determine the matching firmware version.

[PATCH 20/21] Use valid channel count in format enumeration.

From: Eliot Blennerhassett <eblennerhassett@audioscience.com>

Since introduction of mono and low latency modes, fixed channel count of 2
is not always valid.  Use reported max_channels instead.

[PATCH 21/21] Fix format validity check.

From: Eliot Blennerhassett <eblennerhassett@audioscience.com>

Sharing and not reinitialising static pcm_hardware struct resulted in
stream format validity flags being incorrectly shared between cards.
Fix and clarify by declaring locally and initialising in the open functions.
