Blackfin Serial Driver: annotate anomalies 05000215 and 05000099
Add some comments for how these anomalies are addressed: 05000215 - UART TX Interrupt Masked Erroneously We always clear ETBEI within last UART TX interrupt to end a string. It is always set when starting a new tx transfer. 05000099 - UART Line Status Register (UART_LSR) Bits Are Not Updated at the Same Time This anomaly affects driver only in POLL code where multi bits of UART_LSR are checked. It doesn't affect current bfin_5xx.c driver.
