Subject: [PATCH v2] ACPI: Move acpi_blacklisted() declaration to asm/acpi.h

The function acpi_blacklisted() is defined only when CONFIG_X86 is
enabled and is only used by X86 arch code. To align with its usage and
definition conditions, move its declaration to asm/acpi.h

Changes since v1:
- v1 link: https://lore.kernel.org/lkml/[email protected]/T/
- Changed the title to "ACPI: Move acpi_blacklisted() declaration to asm/acpi.h"
- Removed the declaration from include/linux/acpi.h

I would replace it with a blank line (to me it seems the above and below are
different groups from semantic point of view, but Rafael may correct me).

I have replaced the v1 that was applied some time ago with this one.

And I have added the blank line as suggested.
