Implemented mec1322's heavysleep in idle task to reduce further EC power down on S3. MEC1322 needs sleep-enabled for all blocks to acheive max power down including UART. Real heavysleep will be effective only when console/uart is not active. To enable this commit, board-specific commit is required. For example, check commit, "Enabling heavysleep idle task at S3". Test: 1. Put device into S3 mode by typing 'powerd_dbus_suspend" in Linux shell. 2. wait at least 1 min till EC console sleeps 3. measure EC power. Since idle task is continuously scheduled, EC will enters/exits to/from heavy sleep mode frequently in S3 and power consumption will be changed dynamically. For acurate power measurement, high-sampling-rate measurement system might be required and using DMM might not give accurate number.
