Apparently, CONFIG_SYS_HZ must be 1000. Change this, and fix the timer
driver to conform to this.

Have the timer implementation export a custom API get_timer_us() for use
by the BCM2835 MMC API, which needs us resolution for a HW workaround.

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.
