FIFO_SIZE:
Indicates the maximum number of bytes that could be revicted by the
controller at one time. This is the maximum number of bytes that may have been
received from the link but not yet DMA d into memory and is also the maximum possible
value that the PICB count will increase by at one time. The FIFO size is calculated based
on factors including the stream format programmed in ISD0FMT register. As the default
value is zero, SW must write to the respective ISD0FMT register to kick of the FIFO size
calculation, and read back to find out the HW allocated FIFO size.
