As cpu.h is another typically widely included file which doesn't need
full access to the softfloat API we can remove the includes from here
as well. Where they do need types it's typically for float_status and
the rounding modes so we move that to softfloat-types.h as well.
As a result of not having softfloat in every cpu.h call we now need to
add it to various helpers that do need the full softfloat.h
definitions.

Real hardware would use an external device to control the power.
But for the moment let's invent instructions in reserved space,
to be used by our custom firmware.

Any one TB will have only one space value. If we change spaces,
we change TBs. Thus BE and BEV must exit the TB immediately.

For system mode, we will need 64-bit virtual addresses even when
we have 32-bit register sizes. Since the rest of QEMU equates
TARGET_LONG_BITS with the address size, redefine everything
related to register size in terms of a new TARGET_REGISTER_BITS.

The MC68040 MMU provides the size of the access that
triggers the page fault.
This size is set in the Special Status Word which
is written in the stack frame of the access fault
exception.
So we need the size in m68k_cpu_unassigned_access() and
m68k_cpu_handle_mmu_fault().
To be able to do that, this patch modifies the prototype of
handle_mmu_fault handler, tlb_fill() and probe_write().
do_unassigned_access() already includes a size parameter.
This patch also updates handle_mmu_fault handlers and
tlb_fill() of all targets (only parameter, no code change).

This is just about the minimum required to enable compilation
without actually executing any instructions. This contains the
HPPACPU structure and the required callbacks, the gdbstub, the
basic translation loop, and a translate_one function that always
results in an illegal instruction.
