acpi: Create a new Kconfig for ACPI
We have several Kconfig options for ACPI, but all relate to specific
functions, such as generating tables and AML code.
Add a new option which controls including basic ACPI library code,
including the lib/acpi directory. This will allow us to add functions
which are available even if table generation is not supported.
Adjust the command to avoid a build error when ACPIGEN is not enabled.
