[PATCH] ASoC: hdmi-codec: use sizeof_field rather than declaring hcp

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Use FIELD_SIZEOF rather than declaring and initializing hcp. Remove
unused variables. Cleans up clang warning:

warning: Value stored to 'hcp' during its initialization is never read
