ACPI 5 introduced I2cSerialBus resource that makes it possible to enumerate
and configure the I2C slave devices behind the I2C controller. This patch
adds helper functions to support I2C slave enumeration.

An ACPI enabled I2C controller driver only needs to call acpi_i2c_register_devices()
in order to get its slave devices enumerated, created and bound to the
corresponding ACPI handle.

Move some code used for parsing ACPI device resources from the PNP
subsystem to the ACPI core, so that other bus types (platform, SPI,
I2C) can use the same routines for parsing resources in a consistent
way, without duplicating code.

With ACPI 5 it is now possible to enumerate traditional SoC
peripherals, like serial bus controllers and slave devices behind
them.  These devices are typically based on IP-blocks used in many
existing SoC platforms and platform drivers for them may already
be present in the kernel tree.

To make driver "porting" more straightforward, add ACPI support to
the platform bus type.  Instead of writing ACPI "glue" drivers for
the existing platform drivers, register the platform bus type with
ACPI to create platform device objects for the drivers and bind the
corresponding ACPI handles to those platform devices.

This should allow us to reuse the existing platform drivers for the
devices in question with the minimum amount of modifications.

This changeset is based on Mika Westerberg's and Mathias Nyman's
work.

ACPI routines for adding and removing device wakeup notifiers are
currently defined in a PCI-specific file, but they will be necessary
for non-PCI devices too, so move them to a separate file under
drivers/acpi and rename them to indicate their ACPI origins.

Drivers may make calls that require the ACPI IPMI driver to have been
initialised already, so make sure that it appears earlier in the build
order.

ACPI 5.0 adds the BGRT, a table that contains a pointer to the firmware
boot splash and associated metadata. This simple driver exposes it via
/sys/firmware/acpi in order to allow bootsplash applications to draw their
splash around the firmware image and reduce the number of jarring graphical
transitions during boot.

With the conversion of atomicio's routines in place (see commits
6f68c91c55e and 700130b41f4), atomicio.[ch] can be removed, replacing
the APEI specific pre-mapping capabilities with the more generalized
versions that drivers/acpi/osl.c provides.

Some firmware will access memory in ACPI NVS region via APEI.  That
is, instructions in APEI ERST/EINJ table will read/write ACPI NVS
region.  The original resource conflict checking in APEI code will
check memory/ioport accessed by APEI via general resource management
mechanism.  But ACPI NVS region is marked as busy already, so that the
false resource conflict will prevent APEI ERST/EINJ to work.

To fix this, this patch record ACPI NVS regions, so that we can avoid
request resources for memory region inside it.
