[Jared D. McNeill]

Module Name:    src
Committed By:   jmcneill

Modified Files:
        src/sys/arch/arm/cortex: gtmr.c

Log Message:
Interrupts are enabled before the timer is configured. Ensure that the
timer is disabled when attaching so it doesn't go crazy between the time
interrupts are enabled and clocks are initialized. My RPI3 makes it
multi-user now.
