[PATCHv4 01/18] ASoC: Samsung: Remove redundant AQUILA driver

[Jassi Brar <jassisinghbrar@gmail.com>]

From: Jassi Brar <jassi.brar@samsung.com>

AQUILA and GONI are essentially the same h/w w.r.t ASoC.
They only differ by the fact that GONI has stereo speaker-out
whereas AQUILA has mono.

The difference can easily be handled in the same MACHINE driver
by making machine-specific runtime changes.
