  3. os/arch/arm/src/amebasmart,armv7-a: Update CPU gating mechanism for SMP 

    - A deadlock was observed when the cpuA which undergo flash operation is trying to gate the other cpuB, but the cpuB is in critical zone (ie. interrupt disabled state), due to waiting for cpuA to pause itself
- This commit fix the deadlock issue by letting cpuA to check and handle any pending pause request at first, so that cpuB can continue it's workflow and exit from critical zone, thus it can handle the gating request from cpuA
