OMAP3630 and OMAP4430 UART IP blocks have a restriction wrt RX FIFO.
Empty RX fifo read causes an abort. OMAP1/2/3 do not have this restriction.
So interoduce a flag in 8250 driver: UPF_NO_EMPTY_FIFO_READ
If this flag is specified for

Nothing wrong with the requirement but I think it would keep 8250.c a
