The _start symbol is already relocated, so do not add the relocation the second
time in c_runtime_cpu_setup.
This fixes e.g. the abort exception handling path, which ended in double fault
due to bad address in VBAR.

The 'XN' execute never bit is set in the pagetables. This will
prevent speculative prefetches to non executable regions. But the
domain permissions are set as master in the DACR register.
So the pagetable attribute for 'XN' is not effective. Change the
permissions to client.
This fixes lot of speculative prefetch aborts seen on OMAP5
secure devices.

This is used in the subsequent patch to setup dram region
