soc/intel/apollolake: Enable UART debug controller on S3 resume
1. Add a new variable to GNVS to store information during S3 suspend
whether UART debug controller is enabled.
2. On resume, read stored GNVS variable to decide if UART debug port
controller needs to be initialized.
3. Provide helper functions required by intel/common UARRT driver for
enabling controller on S3 resume.
