ArmVirtPkg/FdtClientDxe: fix check for size of "reg" properties 

Currently, the code in FdtClientDxe assumes #address-cells/#size-cells
values of <2>. Since DT "reg" properties always consist of <base, size>
tuples, this means the size of the entire property should always be a
multiple of 16 bytes (i.e, 4 * sizeof(UINT32), not 8. So fix this.
