Subject: [PATCH 09/14] ASoC: remove unused davinci support

From: Arnd Bergmann <arnd@...db.de>

The dm644x and dm3xx SoCs have been removed, as have the
da850_evm/da830_evm machines, the remaining machines all use the
DT based probing and do not use the vcif driver.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
