8250 Serial Driver: Added support for 8250-class UARTs in HV Sistemas H8606 board

Browse Source 
Added support for 8250-class UARTs in HV Sistemas H8606 board,
modification in 8250.c driver for correct compilation with Blackfin

Besides, I think that there is more people using 8250-class UARTs
with a different hardware than the H8606 board. This code can be shared
by them.
