drivers: xds110: Clean up command syntax and documentation 

Arrange all commands under a top level xds110 command. Fix
documentation to properly reflect the current functionality.

Also updated the links in the document to the new permanent
links for the XDS110 only support.

Patch updated for comments from code review. Return
ERROR_COMMAND_SYNTAX_ERROR for wrong number of args in
commands. Added deprecated commands to src/jtag/startup.tcl.

@item @b{TI XDS110 Debug Probe}
@* The XDS110 is included as the embedded debug probe on many Texas Instruments
LaunchPad evaluation boards.
@* The XDS110 is also available as a stand-alone USB debug probe. The XDS110
stand-alone probe has the additional ability to supply voltage to the target
board via its AUX FUNCTIONS port. Use the
@command{xds110_supply_voltage <millivolts>} command to set the voltage. 0 turns
off the supply. Otherwise, the supply can be set to any value in the range 1800
to 3600 millivolts.

LaunchPad evaluation boards. The XDS110 is also available as a stand-alone USB
debug probe with the added capability to supply power to the target board. The
following commands are supported by the XDS110 driver:
@*@deffn {Config Command} {xds110 serial} serial_string
Specifies the serial number of which XDS110 probe to use. Otherwise, the first
XDS110 found will be used.
@end deffn
@*@deffn {Config Command} {xds110 supply} voltage_in_millivolts
Available only on the XDS110 stand-alone probe. Sets the voltage level of the
XDS110 power supply. A value of 0 leaves the supply off. Otherwise, the supply
can be set to any value in the range 1800 to 3600 millivolts.
@end deffn
@*@deffn {Command} {xds110 info}
Displays information about the connected XDS110 debug probe (e.g. firmware
version).
@end deffn
