powerpc: remove MBX and MBX860T boards support

Browse source 
Enough time has passed since these boards were moved to Orphan. Remove.

 - Remove board/mbx8xx/*
 - Remove include/configs/{MBX.h,MBX860T.h}
 - Clean-up if defined(CONFIG_MBX)
 - Move the entries from boards.cfg to doc/README.scrapyard

IMPORTANT NOTE - read before defining CONFIG_SYS_USE_OSCCLK in your board
config file!!!
WARNING: Wrong settings of this parameter have the potential to
damage hardware by running the MBX's CPU at frequencies that exceed
it's rating and/or overdriving the it's SPLL!
Ramblings:
1) Motorola offered 12 different variants of the MBX, 6 823s and 6 860s.
2) Of these 12 variants, only 2 were entry level boards.
3) I believe that the 2 entry level boards were the only ones that
used OSCM clocking. I can't be completely certain of this at this
point.
4) Motorola never offered an MBX that ran faster than 50Mhz.
5) The 10, non-entry level boards, ran at 40Mhz.
6) The EXTCLK input has a minimum clock of 15Mhz for the 823/860.
7) Motorola no longer sells MBXs.
Based on this information, I can surmise that the default power-on
reset clocking was one of the following three options.
Multiplier SPLL Options
------------------------------------
513 OSCM is SPLL input
5 OSCM is SPLL input
1 EXTCLK is SPLL input
The forth option:
5 EXTCLK is SPLL input
is not possible on MBXs. This is because the minimum EXTCLK input
frequency is 15Mhz. 5 * 15Mhz = 75 Mhz. There was no variant that ran
above 50 Mhz.
The board I have borrowed definitely uses a multiplier of 1 for
EXTCLK and runs at 40Mhz. I even went so far as to put a scope on it.
One of the two default OSCM modes are most likely what was used on
the entry level boards to cheapen them by eliminating the external
crystal oscillator.
To add insult to injury, the stupid 860 PLPRCR register retains it's
multiplication factor through hard resets. You can't clear it out
because it is battery backed and once it is set wrong, it stays
wrong. The only way to reset it, so that it takes on it's default
multiplier is to disconnect all power including external, batteries,
as well discharging caps on the board. This precludes the fact that
your 860 may be quite DEAD by this time!
If you don't setup the multiplication factor for boards that use the
OSCM input, they won't run correctly, but at least they won't be
dead.
Addtionally, there is no good way to determine the clock input source
from CPU register data. The only way to deal with this is either hard
code it, determine the correct value with some rather NASTY timing
loops, or try to grok it from external data sources. Motorola
firmware opts for the NASTY timing loops, but needs to configure the
serial ports to do so.
You may have a legitimate need to define CONFIG_SYS_USE_OSCCLK if your
MBX8xx board is using the OSCM clocking mode.
You better know what you are doing here.
