    x86: use car_(get|set)_var accessors for apic timer
    
    The timer_fsb variable was not correctly being accessed in the
    presence of cache-as-ram. The cache-as-ram backing store could
    be torn down but then udelay() could be called causing hangs from
    accessing variables that have unknown values.
    
    Instead change the timer_fsb variable to g_timer_fsb and obtain
    the value through a local access method that does the correct things
    to obtain the correct value.
