ASoC: wm8737: Replace TLV_DB_RANGE_HEAD with DECLARE_TLV_DB_RANGE

DECLARE_TLV_DB_RANGE() has the advantage over using TLV_DB_RANGE_HEAD()
that it automatically calculates the number of items in the TLV and is
hence less prone to manual error.

Generate using the following coccinelle script

// <smpl>
