soc/intel/apollolake: Clean up code by using common System Agent module
This patch currently contains the SA initialization required for bootblock phase - 1. Use SOC_INTEL_COMMON_BLOCK_SA kconfig for common SA code. 2. Perform PCIEXBAR programming based on soc configurable PCIEX_LENGTH_xxxMB 3. Use common systemagent header file.
