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.
