finish removing deprecated/obsolete commands

It's been about a year since these were deprecated and, in most
cases, removed.  There's no point in carrying that documentation,
or backwards compatibility for "jtag_device" and "jtag_speed",
around forever.  (Or a few remnants of obsolete code...)

Removed a few obsolete uses of "jtag_speed":

 - The Calao stuff hasn't worked since July 2008.  (Those Atmel
   targets need to work with a 32KHz core clock after reset until
   board-specific init-reset code sets up the PLL and enables a
   faster JTAg clock.)
 - Parport speed controls don't actually work (tops out at about
   1 MHz on typical HW).
 - In general, speed controls need to live in board.cfg files (or
   sometimes target.cfg files), not interface.cfg ...

@chapter Deprecated/Removed Commands
@cindex Deprecated/Removed Commands
Certain OpenOCD commands have been deprecated or
removed during the various revisions.
Upgrade your scripts as soon as possible.
These descriptions for old commands may be removed
a year after the command itself was removed.
This means that in January 2010 this chapter may
become much shorter.
@itemize @bullet
@item @b{arm7_9 fast_writes}
@cindex arm7_9 fast_writes
@*Use @command{arm7_9 fast_memory_access} instead.
@xref{arm7_9 fast_memory_access}.
@item @b{endstate}
@cindex endstate
@*An buggy old command that would not really work since background polling would wipe out the global endstate
@item @b{arm7_9 force_hw_bkpts}
@*Use @command{gdb_breakpoint_override} instead. Note that GDB will use hardware breakpoints
for flash if the GDB memory map has been set up(default when flash is declared in
target configuration). @xref{gdb_breakpoint_override}.
@item @b{arm7_9 sw_bkpts}
@*On by default. @xref{gdb_breakpoint_override}.
@item @b{daemon_startup}
@*this config option has been removed, simply adding @option{init} and @option{reset halt} to
the end of your config script will give the same behaviour as using @option{daemon_startup reset}
and @option{target cortex_m3 little reset_halt 0}.
@item @b{dump_binary}
@*use @option{dump_image} command with same args. @xref{dump_image}.
@item @b{flash erase}
@*use @option{flash erase_sector} command with same args. @xref{flash erase_sector}.
@item @b{flash write}
@*use @option{flash write_bank} command with same args. @xref{flash write_bank}.
@item @b{flash write_binary}
@*use @option{flash write_bank} command with same args. @xref{flash write_bank}.
@item @b{flash auto_erase}
@*use @option{flash write_image} command passing @option{erase} as the first parameter. @xref{flash write_image}.
@item @b{jtag_device}
@*use the @command{jtag newtap} command, converting from positional syntax
to named prefixes, and naming the TAP.
@xref{jtag newtap}.
Note that if you try to use the old command, a message will tell you the
right new command to use; and that the fourth parameter in the old syntax
was never actually used.
OLD: jtag_device 8 0x01 0xe3 0xfe
-irlen 8 -ircapture 0x01 -irmask 0xe3
@end example
@item @b{jtag_speed} value
@*@xref{JTAG Speed}.
Usually, a value of zero means maximum
speed. The actual effect of this option depends on the JTAG interface used.
@itemize @minus
@item wiggler: maximum speed / @var{number}
@item ft2232: 6MHz / (@var{number}+1)
@item amt jtagaccel: 8 / 2**@var{number}
@item jlink: maximum speed in kHz (0-12000), 0 will use RTCK
@item rlink: 24MHz / @var{number}, but only for certain values of @var{number}
@comment end speed list.
@end itemize
@item @b{load_binary}
@*use @option{load_image} command with same args. @xref{load_image}.
@item @b{run_and_halt_time}
@*This command has been removed for simpler reset behaviour, it can be simulated with the
following commands:
reset run
sleep 100
@end smallexample
@item @b{target} <@var{type}> <@var{endian}> <@var{jtag-position}>
@*use the create subcommand of @option{target}.
@item @b{target_script} <@var{target#}> <@var{eventname}> <@var{scriptname}>
@*use <@var{target_name}> configure -event <@var{eventname}> "script <@var{scriptname}>"
@item @b{working_area}
@*use the @option{configure} subcommand of @option{target} to set the work-area-virt, work-area-phy, work-area-size, and work-area-backup properties of the target.
