Corrently acpi/acpi_bus.h is included in linux/acpi.h only if
CONFIG_ACPI is set, but it contains declarations that are useful
otherwise too.

For consistency, modify linux/acpi.h to always include acpi/acpi_bus.h
and update the latter to avoid exposing too much when CONFIG_ACPI is
not set.

Since acpi_has_method() is called from some code build when
CONFIG_ACPI is unset, add a stub for it to the !CONFIG_ACPI
block in acpi/acpi_bus.h.

I was planning to just pull acpi_device_hid() out so that I can get rid
of CONFIG_ACPI in [1]. This looks much more elegant. Thanks for doing it.

Anytime, and thank you!
