ACPI: Handle CONFIG_ACPI=n better from linux/acpi.h 

linux/acpi.h is the top level header for interfacing
with the ACPI sub-system, so acpi_disabled should be
up there instead of down in asm/acpi.h -- particularly
since asm/acpi.h doesn't exist for all architectures.

Same story for acpi_table_parse(), which is a top-level
API to Linux/ACPI.

This is necessary for building some code that
used to always depend on CONFIG_ACPI=y, but will soon
also need to build with CONFIG_ACPI=n.
