hdat/spira: export abc and wxyz bus speeds
One of the spira structs (iplparams_sysparams) captures
different system bus speeds/frequency. Patch exports the
same in "sys-params" dt node. These values will help in
nest pmu metric calculations.
ABC bus speed values are exported in "abc-bus-freq-mhz"
property. As name suggest, values are in MHz.
WXYZ bus speed values are exported in "wxyz-bus-freq-mhz"
property. As name suggest, values are in MHz.
