The PowerPC 405EZ SoC has some differences in the interrupt layout and
handling for the MAL.  The SERR, TXDE, and RXDE interrupts are OR'd into
a single interrupt.  Also, due to the possibility for interrupt coalescing,
the TXEOB and RXEOB interrupts require an interrupt bit to be cleared in
the ICINTSTAT SDR.

This sets the proper MAL feature bits for 405EZ boards, and adds a common
shared handler for SERR, TXDE, and RXDE.  The defines for the ICINTSTAT DCR
are added to the proper header file as well.

This has been adapted from code originally written by Stefan Roese.

from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.

This patch adds support for the 256k L2 cache found on some IBM/AMCC
4xx PPC's. It introduces a common 4xx SoC file (sysdev/ppc4xx_soc.c)
which currently "only" adds the L2 cache init code. Other common 4xx
stuff can be added later here.

The L2 cache handling code is a copy of Eugene's code in arch/ppc
with small modifications.

Tested on AMCC Taishan 440GX.

Accessing indirect DCRs is done via a pair of address/data DCRs.

Such accesses are thus inherently racy, vs. interrupts, preemption
and possibly SMP if 4xx SMP cores are ever used.

This updates the mfdcri/mtdcri macros in dcr-native.h (which were
so far unused) to use a spinlock.

In addition, add some common definitions to a new dcr-regs.h file.
