ACPI / IBFT: Fix incorrect <acpi/acpi.h> inclusion in iSCSI boot firmware module
To avoid build problems and breaking dependencies between ACPI header
files, <acpi/acpi.h> should not be included directly by code outside
of the ACPI core subsystem, but this is done by the ACPI iSCSI
Boot Firmware code.
The iBFT specification doesn't mention whether or not it can appear
on a non-ACPI platform, but is says that ACPI 3.0b defines the
mechanism. The current CONFIG_ISCSI_IBFT_FIND code doesn't use the
ACPI tables API to locate the table, so it doesn't rely on CONFIG_ACPI
directly.
However, since iBFT is is an ACPI-based mechanism (please refer to
the documentation link below for more information), it should be
correct to make CONFIG_ISCSI_IBFT_FIND depend on CONFIG_ACPI (even
though the table location can be implemented without using ACPI
tables API).
After that change, include/linux/iscsi_ibft.h can be modified to
include <linux/acpi.h> instead of <acpi/acpi.h> as appropriate.
