ArmVirtPkg/FdtClientDxe: add methods to iterate over memory nodes

Browse Source 
Add high level methods to iterate over all 'reg' properties of all DT
nodes whose device_type properties have the value "memory". Since we are
modifying the FdtClient protocol, update the protocol and the only existing
implementation at the same time.
