power/mt8192: set correct initial power state for EFS2
In EFS2, the boot flow happens in RW, so we should not set power state to S0 by default. BUG=b:185726892 TEST=1. Verify AP bootable and able to update EC-RW in following scenarios: a. old RW b. corrupted (not-bootable) RW 2. DISABLE_EC_SOFTWARE_SYNC vboot flag works. 3. manual sysjump won't reboot AP.
