Fwiw, the board or machine driver (when selected) currently selects it's
audio interface driver and DMA driver. The board/machine driver does
however depend on the selected MACH_MACHINE (e.g. MACH_POODLE for Sharp
Poodle) so it only exposes a single y,m,n Kconfig selection for audio as
it's completely platform specific.

The ASoC git tree dev branch does the opposite, as everything can be
selected for quicker build/debug.
