CRIS v32: Update boot/rescue/head.S code. - Add ifdef for ETRAX_AXISFLASHMAP to avoid compiling file unless it is set. - Use assembler macros for setting up clocks. - Don't copy image, just jump to it (only works for NOR flash)

/*
* Just get started by jumping to CONFIG_ETRAX_PTABLE_SECTOR to start
* kernel decompressor.
*
* In practice, this only works for NOR flash (or some convoluted RAM boot)
* and hence is not really useful for Artpec-3, so it's Etrax FS / NOR only.
