Merge branches 'acpica' and 'acpi-tables'
* acpica:
ACPICA: Update version to 20200430
ACPICA: Fix required parameters for _NIG and _NIH
ACPICA: Dispatcher: add status checks
ACPICA: Disassembler: ignore AE_ALREADY_EXISTS status when parsing create operators
ACPICA: Move acpi_gbl_next_cmd_num definition to acglobal.h
ACPICA: Make acpi_protocol_lengths static
* acpi-tables:
ACPI: sleep: Put the FACS table after using it
ACPI: scan: Put SPCR and STAO table after using it
ACPI: EC: Put the ACPI table after using it
ACPI: APEI: Put the HEST table for error path
ACPI: APEI: Put the error record serialization table for error path
ACPI: APEI: Put the error injection table for error path and module exit
ACPI: APEI: Put the boot error record table after parsing
ACPI: watchdog: Put the watchdog action table after parsing
ACPI: LPIT: Put the low power idle table after using it
