serial: qcom_geni_serial: use DT aliases according to DT bindings

Browse source 
Device tree bindings do not specify "hsuart" aliases, instead all serial
ports should use "serial" alias name as noted by Rob Herring [1].
Make qcom_geni_serial driver use "serial" alias and fallback to "hsuart"
if one is not found.
