[PATCH 3/8] ASoC: Intel: catpt: Drop redundant signature argument

[Cezary Rojewski <cezary.rojewski@intel.com>]

Initial design assumed the mechanism could be reused for loading
external modules with signatures differing from the Intel's constant. No
users with such characteristics ever appeared rendering the 'signature'
argument useless.
