Subject: [PATCH 0/2] Convert davinci ASoC to genalloc SRAM

This series converts davinci ASoC to use genalloc and enables
that support on DA850. It applies on top of the uio_pruss/genalloc
series [1] which allows DaVinci to provide a gen_pool via pdata
for driver use.

I've tested this on the AM180x EVM. Note that prior to this,
the SRAM paths in the driver were completely unused. I've only
enabled ping-pong buffering on the platform I can test as it's
best to allow those with DM644x and similar platforms to set the
playback/capture sram size to something that's known to work
for them.

  ASoC: davinci: replace private sram api with genalloc
  ARM: davinci: enable SRAM ping ping buffering on DA850
