kconfig: optionally check if the ACPI info header is validated

Browse Source 
Instead of using the ACPI info template in the source tree, this patch requires
a board-specific ACPI info header to be created by the user and placed under
bsp/include. Currently we'll fall back to the current platform-specific template
if such board-specific info is not available.

A configuration symbol ACPI_ENFORCE_VALIDATED_ACPI_INFO is also added to enforce
the existance of board-specific ACPI info header. Default configurations can set
this symbol if the template does not work on a board.

Updates to the getting started guide will be updated accordingly after the
offline tools to generate such header is available.

v2 -> v3:

* Rephrase the ACPI-info-related messages.

v1 -> v2:

* The generated header should depend on .config so that whenever any
  configuration changes, this header will be remade.

When set, validated ACPI info tables is enforced and using offline
tools to generate such data is required. Otherwise a warning will be
printed when validated ACPI info is unavailable, but a binary can
still be built with the ACPI info template.
