To be more EABI compliant and as a preparation for building with clang, use the platform-specific r9 register for gd instead of r8.

This patch assumes only crt0.S sets the register used for gd in asm. I just noticed cpu/armv7/lowlevel_init.S does set gd manually, so all users of the common board.c are likely bricked with the patch as is. Looking into it....
