ARM: tegra: cpuidle: Make abort_flag atomic

Browse source

Replace memory accessors with atomic API just to make code consistent
with the abort_barrier. The new variant may be even more correct now
since atomic_read() will prevent compiler from generating wrong things
like carrying abort_flag value in a register instead of re-fetching it
from memory.
