arm64: smp: honour #address-size when parsing CPU reg property
For systems where the top 32-bits of the MPIDR are all zero, we should allow the device-tree to specify an #address-size of 0x1 for the CPU reg property and then zero extend the value there. Without this patch, kvmtool breaks with the recent mpidr parsing code introduced in 4c7aa002 ("arm64: kernel: initialise cpu_logical_map from the DT").
