d307d36ade tty: Blackin CTS/RTS
Both software emulated and hardware based CTS and RTS are enabled in
serial driver.

The CTS RTS PIN connection on BF548 UART port is defined as a modem
device not as a host device.  In order to test it under Linux, please
nake a cross UART cable to exchange CTS and RTS signal.

97d4b35fb4 Blackfin arch: fix bug - Error if one serial has hardware flow control and the other doesn't
I have a system where UART0 is configured with hardware flow control, but UART1
doesn't have it enabled. Attempting to access UART1 in this configuration
results in the following error in dmesg:

<3>bfin-gpio: GPIO 0 is already reserved as Peripheral by bfin-uart !

This is because the #ifdef's in bfin_serial_5xx.h are messed up. More
specifically, they add/remove the uart_{rts,cts}_pin fields in
bfin_serial_resources based on whether the particular port has rts/cts enabled,
as opposed to when either port has it enabled.

This patch fixed this.
