avr: move data address space to 0x800000

Browse Source 
This convention is followed by most of the avr-gcc toolchain but older
versions of binutils don't mind overlapping program/data spaces.
However, newer versions start complaining about an overlap in address
space:

    avr-ld: section .stack VMA [0000000000000100,00000000000002ff] overlaps section .text VMA [0000000000000000,0000000000000225]

This commit moves the data space in the linker script to 0x800000, like
the rest of the toolchain does.
