commit 443d372d6a upstream.
Although the IRQ assignment in ipmi_si driver is optional,
platform_get_irq() spews error messages unnecessarily:
ipmi_si dmi-ipmi-si.0: IRQ index 0 not found
Fix this by switching to platform_get_irq_optional().

ipmi_si_sm.h was getting included in lots of places it didn't
belong. Rework things a bit to remove all the dependencies,
mostly just moving things between include files that were in
the wrong place and removing bogus includes.

Plus add a driver that allows Linux to act as an IPMB slave device,
so it can be a satellite MC in an IPMI network.

There is an arbitrary difference between the prototypes of
bus_find_device() and class_find_device() preventing their callers
from passing the same pair of data and match() arguments to both of
them, which is the const qualifier used in the prototype of
class_find_device(). If that qualifier is also used in the
bus_find_device() prototype, it will be possible to pass the same
match() callback function to both bus_find_device() and
class_find_device(), which will allow some optimizations to be made in
order to avoid code duplication going forward. Also with that, constify
the "data" parameter as it is passed as a const to the match function.
For this reason, change the prototype of bus_find_device() to match
the prototype of class_find_device() and adjust its callers to use the
const qualifier in accordance with the new prototype of it.

If ipmi_si_platform_init()->platform_driver_register() fails,
platform_driver_unregister() called unconditionally will trigger
following warning,
ipmi_platform: Unable to register driver: -12

Unexpected driver unregister!
WARNING: CPU: 1 PID: 7210 at drivers/base/driver.c:193 driver_unregister+0x60/0x70 drivers/base/driver.c:193
Fix it by adding platform_registered variable, only unregister platform
driver when it is already successfully registered.

It was being done in two different places now that hard-coded devices
use platform devices, and it's about to be three with hotmod switching
to platform devices. So put the code in one place.
This required some rework on some interfaces to make the type space
clean.

When excuting a command like:
modprobe ipmi_si ports=0xffc0e3 type=bt
The system would get an oops.
The trouble here is that ipmi_si_hardcode_find_bmc() is called before
ipmi_si_platform_init(), but initialization of the hard-coded device
creates an IPMI platform device, which won't be initialized yet.
The real trouble is that hard-coded devices aren't created with
any device, and the fixup is done later. So do it right, create the
hard-coded devices as normal platform devices.
This required adding some new resource types to the IPMI platform
code for passing information required by the hard-coded device
and adding some code to remove the hard-coded platform devices
on module removal.
To enforce the "hard-coded devices passed by the user take priority
over firmware devices" rule, some special code was added to check
and see if a hard-coded device already exists.

The IPMI spec states:
The purpose of the SPMI Table is to provide a mechanism that can
be used by the OSPM (an ACPI term for “OS Operating System-directed
configuration and Power Management” essentially meaning an ACPI-aware
OS or OS loader) very early in the boot process, e.g., before the
ability to execute ACPI control methods in the OS is available.
When we are probing IPMI in Linux, ACPI control methods are available,
so we shouldn't be probing using SPMI. It could cause some confusion
during the probing process.

Rework the DMI probe function to be a generic platform probe, and
then rework the DMI code (and a few other things) to use the more
generic information. This is so other things can declare platform
IPMI devices.
