[PORT FROM R2] EM/BCU: Fix Sysburst behaviour in driver's suspend/resume path

BZ: 18257

The intel_mid_ocd driver disables only the SYSACTEN bit during suspend.
But the SYSOUTEN signal can still be triggered by GSMPULSE (due to
hardware logic design). This patch corrects this behaviour by disabling
both the SYSACTEN and SYSOUTEN bits during suspend and programs these
bits according to battery_level during resume.
