[alsa-devel] [alsa-lib][PATCH 1/2] ucm: adding the folder of card_long_name when finding verb conf file

The board configuration file and verb conf file are allowed to be
in the folder named of card_long_name, so when finding the verb conf
file, we need to check if it is in the folder of card_long_name or
card_name.
