Kirkwood: print_cpuinfo fixed for valid devid revid
Earlier Device Identification register was used to detect
the type for SoC, considering 88F6282 support to be added,
It is not possible to detect the same using current
algorithm.
With this patch, device ID is being read using PCIE devid
register, also valid chip revision ID will also be read and
displayed
