2018-08-20soc/intel/common/block: Move common uart function to block/uartSubrata Banik
This patch moves uart functions which are common across multiple soc to block/uart. This will remove redundant code copy from soc {skylake/apollolake/cannonlake}. BUG=b:78109109 BRANCH=none TEST=Build and boot on KBL/APL/CNL platform.

2017-12-14soc/intel/cannonlake: Fix UART2 serial log broken issueSubrata Banik
Cannonlake rvp serial log has been regressed with commit I7eea910e065242689e87adac41281131674b39af(soc/intel/cannonlake: Clean up UART code) because of common UART code is unable to link all __weak function implementation from SoC uart.c due to existing macro #define __SIMPLE_DEVICE__. Hence UART2 PCI device resource programming is different than what it's been programmed before. This patch ensures UART2 PCI device resource enumeration is working and we are getting serial log as expected.
