serial: qcom_geni_serial: use DT aliases according to DT bindings 

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.
