[RFC 1/2] ASoC: Add new SOC_DOUBLE*_ACCESS() macros

[Hans de Goede]

Add 3 new SOC_DOUBLE*_ACCESS() macros:

SOC_DOUBLE_ACCESS()
SOC_DOUBLE_EXT_ACCESS()
SOC_DOUBLE_TLV_ACCESS()

These work the same as their non _ACCESS postfixed counter-parts,
with an extra argument that allows specifying extra access flags.

This is meant to be used with the new SNDRV_CTL_ELEM_ACCESS_*_LED flags.
