    google/gale: Turn on monotonic timer support
    
    Without monotonic timer support, timer related APIs like
    timer_monotonic_get etc. are optimized out by the compiler. This
    results in timed loops to become indefinite loops
    
    	stopwatch_init_msecs_expire(...);
    	do {
    		something();
    	} while (!stopwatch_expired(...));
    
    In our specific case, loops sampling the recovery/wipeout button
    in src/mainboard/google/gale/chromeos.c:get_switch_state() turned
    into infinite loops and the boot didn't proceed.
    
    BUG=chrome-os-partner:49249
    TEST=Confirmed that the loop breaks per the specified timeout
    using the minicom's console log time stamps
    	[2016-04-11 12:34:37] recovery button pressed
    	[2016-04-11 12:34:45] wipeout requested, checking recovery
    	[2016-04-11 12:34:53] recovery requested
    BRANCH=none
