bug #28744: Can't load bootloader to xmega128a1 (part 2, fix for

firmware >= V7.x)
* jtagmkII.c: Add firmware-version dependent handling of Xmega parameters.
V7.x firmware expects the NVM offsets being specified through the Xmega
parameters command, but left out as part of the memory address itself.
* jtagmkII_private.h: Add CMND_SET_XMEGA_PARAMS, and struct xmega_device_desc.
* config_gram.y: Add mcu_base keyword.
* avrpart.h: (Dito.)
* lexer.l: (Dito.)
* avrdude.conf.in (.xmega): add mcu_base, and data memory segment.
