soc/intel/common: Add support for serial console based ACPI debug
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.
