    clocksource/fsl: Avoid harmless 64-bit warnings · dde7632e

    The ftm_clockevent_init passes the value of "~0UL" into a function
    that takes a 32-bit argument, which drops the upper 32 bits, as
    gcc warns about on ARM64:
    
    clocksource/fsl_ftm_timer.c: In function 'ftm_clockevent_init':
    clocksource/fsl_ftm_timer.c:206:13: warning: large integer implicitly truncated to unsigned type [-Woverflow]
    
    This was obviously unintended behavior, and is easily avoided by
    using '~0u' as the integer literal, because that is 32-bit wide
    on all architectures.
