This is long over due.  All but two net drivers have been converted, but
those have now been dropped.

The only thing left to do is actually delete all references to NET_MULTI
and code that is compiled when that is not defined.  So here we scrub the
core code.

This patch starts a bit PPC4xx header cleanup. First patch mostly
touches PPC440 files. A later patch will touch the PPC405 files as well.

This cleanup is done by creating header files for all SoC versions and
moving the SoC specific defines into these special headers. This way the
common header ppc405.h and ppc440.h can be cleaned up finally.

This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:

- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
  user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines

Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.

It was brought to our attention that U-Boot contains code derived from the
IBM OpenBIOS source code originally provided with some of the older PowerPC
4xx development boards.  As a result, the original license of this code has
been carried in the various files for a number of years in the U-Boot project.

IBM is dual-licensing the IBM code contributions already present in U-Boot
under either the terms of the GNU General Public License version 2, or the
original code license already present.

This patch fixes a compilation warning for some Ethernet PHY-less
PPC4xx platforms (440SPE based ones) and a potential compilation
error for 440SP platforms (use of undefined 'ethgroup' variable).
In the original code and in case of 440SPE platforms, 'ethgroup'
is initialized to -1 and never modified.  Later in the function,
within an #ifdef statement, an 'if statement' executes code only
if 'ethgroup' is set to 4, therefore it is harmless to avoid
executing the 'if statement' by removing the CONFIG_440SPE from
the affected #ifdefs.  In case of 440SP platforms  with on-board
Ethernet PHY, 'ethgroup' is undefined but used (there are not such
platforms in the repository yet). All other architectures are not
affected by this change.

This patch fixes MDIO clock setup in case when OPB frequency is 100MHz.
Current code assumes that the value of sysinfo.freqOPB is 100000000
when OPB frequency is 100MHz. In reality it is 100000001. As a result
MDIO clock is set to incorrect value, larger than 2.5MHz, thus violating
the standard. This in not a problem on boards equipped with Marvell PHYs
(e.g. Canyonlands), since those PHYs support MDIO clocks up to 8.3MHz,
but can be a problem for other PHYs (e.g. Realtek ones).

This patch reworks the 440GX interrupt handling so that the common 4xx
code can be used. The 440GX is an exception to all other 4xx variants
by having the cascading interrupt vectors not on UIC0 but on a special
UIC named UICB0 (UIC Base 0). With this patch now, U-Boot references
the 440GX UICB0 when UIC0 is selected. And the common 4xx interrupt
handling is simpler without any 440GX special cases.

Also some additional cleanup to cpu/ppc4xx/interrupt.c is done.

This 2nd patch now removes all UIC mask bit definition. They should be
generated from the vectors by using the UIC_MASK() macro from now on.
This way only the vectors need to get defined for new PPC's.

Also only the really used interrupt vectors are now defined. This makes
definitions for new PPC versions easier and less error prone.

Another part of this patch is that the 4xx emac driver got a little
cleanup, since now the usage of the interrupts is clearer.
