Different personalities/derivatives of SoC may have reduced cluster. But it is
not necessary for last valid DCFG_CCSR_TP_CLUSTER register to have
DCFG_CCSR_TP_CLUSTER[EOC] bit set to represent "End of Clusters".

EOC bit can still be set in last DCFG_CCSR_TP_CLUSTER register of orignal SoC
which may not be valid for the personality.
So add initiator type check to find valid cluster.

B4420 is a reduced personality of B4860 with fewer core/clusters(both SC3900
and e6500), fewer DDR controllers, fewer serdes lanes, fewer SGMII interfaces and
reduced target frequencies.

Key differences between B4860 and B4420
----------------------------------------
B4420 has:
1. Fewer e6500 cores: 1 cluster with 2 e6500 cores
2. Fewer SC3900 cores/clusters: 1 cluster with 2 SC3900 cores per cluster.
3. Single DDRC
4. 2X 4 lane serdes
5. 3 SGMII interfaces
6. no sRIO
7. no 10G

By now U-Boot supports Qemu MIPS for little and big endian

in the README to reflect this.
Signed-off-by: NDaniel Schwierzeck <daniel.schwierzeck@gmail.com>

Using the example command from the README file does
not work as expected. qemu shows a text similar to
the one below and it hangs.

    $ qemu-system-mips -L . -nographic
    Could not open option rom 'pxe-pcnet.rom': No such file or directory
    qemu-system-mips: pci_add_option_rom: failed to find romfile "vgabios-cirrus.bin"
    qemu: terminating on signal 15 from pid 19726

This happens because qemu emulates a Malta board by
default if the machine type is not defined explicitely
on the command line.

For a working test, the '-M mips' switch is required:

    $ qemu-system-mips -M mips -L . -nographic
    Could not open option rom 'vgabios.bin': No such file or directory

The 'Limitations & comments' section refers to the
'-m mips' switch which is not valid. The '-m' switch
can be used for setting the virtual RAM size:

    $qemu-system-mips --help | grep '^-m '
    -m megs         set virtual RAM size to megs MB [default=128]
    $

The correct switch for specifying the machine type is '-M'.
