ARM: warp7_mbl_defconfig: Temporarily switch on HZ_PERIODIC
We need to update to v4.14.71 to mitigate a cache-timing exploit.

Updating to 4.14.71 produces the following error on our board though.
NOHZ: local_softirq_pending 40
Upstream doesn't have this problem so. As a workaround in the meantime we
can move to CONFIG_HZ_PERIODIC which fixes the issue.
