target-sh4: implement writes to mmaped ITLB

Some Linux kernels seems to implement ITLB/UTLB flushing through by
writing all TLB entries through the memory mapped interface instead
of writing one to MMUCR.TI.

Implement memory mapped ITLB write interface so that such kernels can...

Add endianness as io mem parameter

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.

This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose...

Replace assert(0) with abort() or cpu_abort()

When building with -DNDEBUG, assert(0) will not stop execution
so it must not be used for abnormal termination.

Use cpu_abort() when in CPU context, abort() otherwise.

Remove io_index argument from cpu_register_io_memory()

The parameter is always zero except when registering the three internal
io regions (ROM, unassigned, notdirty). Remove the parameter to reduce
the API's power, thus facilitating future change.

SH4: Eliminate P4 to A7 mangling (Takashi YOSHII).

Main purpose of this is to delete

This masking is a nice trick to realize P4/A7 duality of SH registers....

[sh4] MMU bug fix

Some bugs on SH4 MMU are fixed.
