[PATCH 12/13] ASoC: Intel: avs: Add assert_static to guarantee ABI sizes

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

From: Amadeusz Sławiński <amadeuszx.slawinski@linux.intel.com>

In order to make sure that IPC interface is stable use assert_static to
check union and struct sizes that describe communication interface.
