Niranjan H Y ba2a0e81d4 ASoC: SDCA: Export Q7.8 volume control helpers
Export the Q7.8 volume control helpers to allow reuse
by other ASoC drivers. These functions handle 16-bit
signed Q7.8 fixed-point format values for volume controls.

Changes include:
- Rename q78_get_volsw to sdca_asoc_q78_get_volsw
- Rename q78_put_volsw to sdca_asoc_q78_put_volsw
- Add a convenience macro SDCA_SINGLE_Q78_TLV and
  SDCA_DOUBLE_Q78_TLV for creating mixer controls

This allows other ASoC drivers to easily implement controls
using the Q7.8 fixed-point format without duplicating code.
