zephyr: remove infinite recursion on Broadwell 

Broadwell support with Zephyr had only been dry-coded, it has never
been tested, and it contains an infinite recursion bug: functions
platform_timer_get() and arch_timer_get_system() call each other
infinitely. Break the recursion formally, until a proper fix is
available.
