n 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.

Passes the DA850 shared SRAM gen_pool to the McASP driver
and enables the ping-pong buffer DMA support.

Removes the DaVinci private SRAM API and replaces it with
the genalloc API. The SRAM gen_pool is passed in pdata since
DaVinci is in the early stages of DT conversion.
