Subject: [PATCH v2 1/5] ASoC: soc.h: Add SOC_SINGLE_S_TLV() macro

Add a convenience macro for defining a single (mono) TLV control
with a signed value. This can already be done by using
SOC_DOUBLE_R_S_TLV() with the same address for left and right
registers, but a dedicated macro is more readable.
