While "flash bank" syntax has been changed long ago,
several tcl script are still not fully update.

Fix following cases related with "cfi" driver:
- syntax error: the mandatory <name> parameter is missing
- warning: the <target> parameter is a number, instead of
  the target name
- the comment line above the command does not report
  actual syntax

Globally rename "jtag_khz" as "adapter_khz", and move it out of the "jtag"
command group ...  it needs to be used with non-JTAG transports

Includes a migration aid (in jtag/startup.tcl) so that old user scripts
won't break.  That aid should Sunset in about a year.  (We may want to
update it to include a nag message too.)

Sets $_FLASHNAME to "$_CHIPNAME.flash" and passes it as the
first argument to 'flash bank'.

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 ...
