2017-06-07intel/common/acpi: Fix ACPI debug log issue with LPSS UARTSubrata Banik
This patch fixes ACPI debug print issue reported internally while using APRT asl method. Potentially some junk characters gets added into final print buffer due to LPSS MMIO register space is 32 bit width and ADBG is one byte at a time. TEST=Built and boo eve to ensure to be able to get ASL console log without any corruption.

2016-08-11soc/intel/common: Add support for serial console based ACPI debugSubrata Banik
This patch enables serial debug functionality for ASL code based on UART type(legacy/LPSS). From Skylake onwards all Intel platform uses LPSS based UART for serial console hence provide option to redirect ASL log over LPSS UART. Example: Name (OBJ, 0x12) APRT (OBJ) APRT ("CORE BOOT") Output: 0x12 CORE BOOT BUG=none BRANCH=none TEST=Built and boot kunimitsu to ensure to be able to get ASL console log.
