[coreboot] New patches for NOKIA-IP530 and 2143PD driver.

[Marc Bertens]

Hi all,

I made some new patches for the Nokia IP530, therefore my last patch
submission can be discarded.

1.    21143PD driver; I removed the not needed stuff from there and
tested without and all worked fine.

2.    Patched the devicetree.cb; added some comments and commented out
the setting of the GPIO lines, this was unnecessary.

3.    nokia/Kconfig; added a description in de help about which board
revisions are supported.

4.    ip530/Kconfig; added the CPU model, removed the PIRQ_ROUTE and set
the IRQ_SLOT_COUNT to 1, this last is needed by the
        header files, because those structures are still used by the
code, see pirq_table.c

5.    ip530/mainboard.c; Now the identification of the physical system
is show in the boot up of the machine, like;
        * System type, should be IP530, otherwise a warning is given. 
        * Board number 
        * Mfg. P/N
        * Mfg. rev.
        * Serial number
        All these read from the SPI eeprom behind the SuperIO

6.    The sourcecode files for the superIO-SPI interface in the
Nokia-IP530.

Stefan: please drop that last patch submission of mine.

Thats all folks....
