pflash: Buffer block writes

Buffer block writes to avoid flushing every word access onto backing
storage device. This significantly speeds up flash emulation for flashes
connected through an 8 or 16-bit bus combined with backing storage (-pflash).

Revert "Get rid of _t suffix"

In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem. Something
like this must be presented on the list first so people can provide input...

Check block driver read error in pflash_cfi0x

If a flash file of size smaller than the flash size is specified in
the -pflash option, the block driver returns error. But the
pflash_cfi0x ignores the error. This results in a flash content of all
zeroes. And the simulation aborts while executing code....

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.

Clean up MMIO TLB handling.
The IO index is now stored in its own field, instead of being wedged

pointer weirdness. The IO index space is expanded by 1 bit, and
several additional bits are made available in the TLB vaddr field....
