spi/bfin_spi: handle error/status changes after data interrupts
The error interrupt on the BF537 SIC cannot be enabled on a
per-peripheral basis. Once the error interrupt is enabled
for one peripheral, it is automatically enabled for all.
So in the Blackfin on-chip SPI driver, we need to clear out
these known errors in the data interrupt once we've successfully
finished processing all of the pending data.
