The patch update arm_arch_timer driver to use the function
provided by the new GTDT driver of ACPI.
By this way, arm_arch_timer.c can be simplified, and separate
all the ACPI GTDT knowledge from this timer driver.

I don't think users expect interrupt, panic or reboot at timeout/2.
And WS1 definitely isn't a backup of WS0.
