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.)

The MC13224V is a FreeScale ARM7TDMI based IEEE802.15.4 platform for
Zigbee and similar low-power wireless applications. Using PIP
(Platform In Package) technology, it integrates: an RF balun and
matching network; a buck converter (only an external inductor is
necessary); 96KB of SRAM; and 128KB of non-volatile memory.

It has an integrated bootloader and can boot from a variety of sources:
external SPI or I2C non-volatile memory, an image loaded over UART1,
or the internal non-volatile memory. The image loaded from one of these
sources is executed directly from SRAM starting at location 0x00400000.
