commit 2502b667ea ("Change the m68knommu irq
handling to use the generic irq framework.") removed the reporting of spurious
interrupts on nommu (68328 and 68360).
Bring it back in a generic way, using "atomic_t irq_err_count", as that's what
most of the other architectures are using.

The ColdFire processors have a much more limited set of addressing modes
that can be used for most instructions. A number of the atomic operations
have already been fixed to limit the addressing modes used with add and
sub instructions when building for ColdFire. But we missed a few.
Fix the remaining atomic operations to be clean for ColdFire processors.

When reworking bitops.h to be clean for all processor types we introduced
a CONFIG_CPU_HAS_NO_BITFIELDS define to signal whether this processor type
supported the bit field instructions. The ARCH_SIG_BITOPS functions for
m68k use these instruction types. We should base the use of these functions
(or the generic versions) on the CONFIG_CPU_HAS_NO_BITFIELDS define.

The real difference between the mmu and non-mmu varients of the delay.h
files has nothing to do with having an mmu or not. It is processor family
differences that means slightly different code. Merge the delay_mm.h and
delay_no.h files back into a single file.
The primarly difference we need to deal with is whether the processor
supports a 32bit * 32bit -> 64bit multiply. Without it we need to do some
shift scaling as well as use a 32bit * 32bit -> 32bit multiply. If building
for a multi-CPU type kernel then we must use the simpler mult/shift scaling.
This version of delay code allows the CPU32 family to use a 64bit mul,
since it supports this instruction, the old code did not.
The changes use macros where appropriate to try and optimize constant sized
udelay times. And it removes the use of a fixed lib function for the non-mmu
case. Code size on typical kernel configurations is similar, or only larger
by a few tens of bytes.
Also removed the unused muldiv() code from delay_mm.h.
Build and run tested on ColdFire and ARAnyM. Build tested only on 68328
and 68360 (CPU32).

Currently trap_init() is an empty function for m68knommu. Instead
the vectors are being setup as part of the IRQ initialization.
This is inconsistent with m68k and other architectures.
Change the local init_vectors() to be trap_init(), and init the
vectors at the correct time during startup. This will help merge of
m68k and m68knommu trap code in the furture.

The ColdFire 5206 and 5206e CPU families are almost identical, we can
easily merge the platform support code for them. All the differences

The following patch merges the mmu and non-mmu versions of the m68k
bitops.h files. Now there is a good deal of difference between the two
files, but none of it is actually an mmu specific difference. It is
all about the specific m68k/coldfire varient we are targeting. So it
makes an awful lot of sense to merge these into a single bitops.h.
There is a number of ways I can see to factor this code. The approach
I have taken here is to keep the various versions of each macro/function
type together. This means that there is some ifdefery with each to handle
each CPU type.
I have added some comments in a couple of appropriate places to try
and make it clear what the differences we are dealing with are.
Specifically the instruction and addressing mode differences we have
to deal with.
The merged form keeps the same underlying optimizations for each CPU
type for all the general bit clear/set/change and find bit operations.
It does switch to using the generic le operations though, instead of
any local varients.
Build tested on ColdFire, 68328, 68360 (which is cpu32) and 68020+.
Run tested on ColdFire and ARAnyM.

The non-MMU m68k targets can use the same asm/system.h as the MMU
targets. So switch the current system_mm.h to be system.h and remove
system_no.h.
The assembly support code for the non-MMU resume functions needs to
be modified to match the now common switch_to() macro. Specifically
this means correctly saving and restoring the status flags in the case
of the ColdFire resume, and some reordering of the code to not use
registers before they are saved or after they are restored.

The non-mmu and mmu versions of the module loader module.c are
