arm: add vexpress board support
detect the cpu model to dynamise the periphs mapping
currently only tested on qemu but should work on real hardware
Cortex-A9
if you use 1GiB of ram you can run the same barebox on Cortex-A15 or Cortex-A9
otherwise use vexpress_ca9_defconfig where the TEXT_BASE is at 0x63f00000
when we will add the relocation support this defconfig will be drop
