Replace the custom SCIx_HAVE_RTSCTS flag in the
plat_sci_port.capabilities field by the standard UPF_HARD_FLOW flag in
the uart_port.flags and plat_sci_port.flags fields.
Remove the now unused plat_sci_port.capabilities field.
Legacy pllatform data can enable UPF_HARD_FLOW in plat_sci_port.flags.
Note that currently nothing sets the SCIx_HAVE_RTSCTS flag.
