[Patch, avr] Add atmel ata5782 and ata5831 devices

This patch adds supports for Atmel's ata5782 and ata5831 devices.

These devices ISA matches with AVR5 architecture except that text section 
start for these two devices is 0x8000. By default 0x0 is used as the text 
start address. This patch adds a device attribute for text start and that 
is passed to Linker via -Ttext option.

If OK, could someone commit please?
