The davinci-mcasp driver will copy the platform data specified sram sizes and eventq's.
Set the event queues and sram sizes for da850. 8K SRAM buffers are selected because it is the minimum that resulted in the same period size when testing 48KHz S16_LE stereo. Event queues 0 and 1 are assigned to match those specified by Troy Kisky in his introduction of ping-pong buffers for dm644x.
