[alsa-lib][PATCHv2] ucm: docs: typeset lists of identifiers explicitly

[Antonio Ospite <ao2@ao2.it>]

Doxygen doesn't preserve formatting that relies only on indentation,
typeset lists of identifiers explicitly.

This makes the HTML docs a lot more readable.

This change comes along the lines of commit 72aa0f8332fb ("ucm: reformat
snd_use_case_get() doc").

Some TABs has been added too in order to preserve the aligned look when
reading the source code.

Signed-off-by: Antonio Ospite <ao2@ao2.it>

Changes since v1:

  * fix a typo where a '=' (equal) was used instead of a '-' (minus) at the
    start of one line.

Thanks,
   Antonio
