[PATCH v3 17/29] x86: Move acpi_table header to main include/ directory

Simon Glass
2020-03-30T23:12:53Z

This file is potentially useful to other architectures saddled with ACPI
so move most of its contents to a common location.

Changes in v3:
- Add forward declarations for the functions
- Move acpi_table.h to include/acpi
- Update commit message to say that we move most of its contents

Changes in v2: None
