ASoC: Intel: avs: Silence false-positive memcpy() warnings

Browse Source 
Commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3") enforced
strict flex array declarations. This generates false-positive in form of:
"memcpy: detected field-spanning write". Avoid it by utilizing the
DECLARE_FLEX_ARRAY() macro.
