drivers/usb_blaster: Group adapter commands

Use a command group 'usb_blaster' with subcommands instead of individual
commands with 'usb_blaster_' prefix.

The old commands are still available for backward compatibility but
marked as deprecated.

 Provides the USB device description (the @emph{iProduct string})

 specified, the FTDI default value is used. This setting is only valid
 if compiled with FTD2XX support.

 The vendor ID and product ID of the FTDI FT245 device. If not specified,
 default values are used.
 Currently, only one @var{vid}, @var{pid} pair may be given, e.g. for
 Altera USB-Blaster (default):
