[PATCH v4 05/10] serial: st-asc: Use generic DT binding for announcing RTS/CTS lines

[Lee Jones]

The initial binding 'st,hw-flow-control' isn't used anywhere, in neither
in upstream nor downstream kernels.  It isn't even documented in
dt-bindings, so we can safely assume it's safe to swap to the generic
one.
