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 4c7aa0021356 ("arm64: kernel: initialise cpu_logical_map
from the DT").
