- Restore some 8052 SFR and bit names that were inadvertently omitted for more advanced models
- Add a few more T2-related names
- Add i8xc51fx and i8xc51gb disassemblers with additional SFR and bit names
- Remove i80c51 from unidasm (actual differences from i8051 are not significant)
Change device names from "Intel I8xxx" to "Intel 8xxx" (nw)
scm_500: Identify CPU type as 80C51GB (specific differences obviously not emulated) (nw)
unidasm: Realphabetize mips1 (nw)

This effectively reverts b380514764cf857469bae61c11143a19f79a74c5 and
c24473ddff715ecec2e258a6eb38960cf8c8e98e, restoring the state at
598cd5227223c3b04ca31f0dbc1981256d9ea3ff.
Before pushing, please check that what you're about to push is sane.
Check your local commit log and ensure there isn't anything out-of-place
before pushing to mainline. When things like this happen, it wastes
everyone's time. I really don't need this in a week when real work™ is
busting my balls and I'm behind where I want to be with preparing for
MAME release.

* create derived 6502 type for XaviX because it has at least one custom 4-byte opcode that doesn't fit any other type.
treating that opcode as NOP for now.
have a feeling it might be something to do with the other integrated hardware, might be 'execute co-processor code chain at this address' or something similar
It isn't a standard JSL (Jump Subroutine Long) like the SNES cpu opcode in the same place as this, it seems to point at some code-like structures tho)
could also be a secondary operation mode with different encoding like ARM's Thumb mode tho I guess.
We currently only have a single XaviX based dump (taitons1) but there are more on the way. I'm going to see if the code flow makes any sense at all with these missing, or if any of it gives a clue as to what they should actually do.
* xavix - let's call these callf and retf then
after further investigation these are some kind of extra 'long jump' subroutine / task handlers, the 0x80 also being a custom opcode was throwing me off trying to identify them before.
looks like they might have been hacking 65816 features into the regular 6502 core?
* prepare for extra address bits (nw)
* better program flow (nw)

- Separate disassembler for i802x (including unemulated 8022 instructions)
- Provide separate (though mostly just more limited) 8021 opcode table
- Writes to 8021 P0 no longer go through memory space

please people, remember to keep source UTF-8 and if you're committing on behalf of others, clean up indents to meet MAME conventions
anyone can run srcclean over a submission and see what will get hit
