ipmi_si: Get rid of ->addr_source_cleanup()

The ->addr_source_cleanup() callback is solely used by PCI driver
and only for one purpose, i.e. to disable device. Get rid of
->addr_source_cleanup() by switching to PCI managed API.

ipmi_si: Rework some include files

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.

ipmi_si_pci: fix NULL device in ipmi_si error message

I noticed that 4.17.0 logs the follwing during ipmi_si setup:

ipmi_si 0000:01:04.6: probing via PCI
(NULL device *): Could not setup I/O space
ipmi_si 0000:01:04.6: [mem 0xf5ef0000-0xf5ef00ff] regsize 1 spacing 1 irq 21

Fix the "NULL device *) by moving io.dev assignment before its potential
use by ipmi_pci_probe_regspacing().

Result:
ipmi_si 0000:01:04.6: probing via PCI
ipmi_si 0000:01:04.6: Could not setup I/O space
ipmi_si 0000:01:04.6: [mem 0xf5ef0000-0xf5ef00ff] regsize 1 spacing 1 irq 21

ipmi: Use more common logging styles

Add and use #define pr_fmt/dev_fmt, and remove #define PFX

This also prefixes some messages that were not previously prefixed.

Miscellanea:

o Convert printk(KERN_<level> to pr_<level>(
o Use %s, __func__ where appropriate

ipmi:pci: Blacklist a Realtek "IPMI" device

Realtek has some sort of "Virtual" IPMI device on the PCI bus as a
KCS controller, but whatever it is, it's not one. Ignore it if seen.

ipmi_si: Fix oops with PCI devices

When the IPMI PCI code was split out, some code was consolidated for
setting the io_setup field in the io structure. The PCI code needed
this set before registration to probe register spacing, though, so
restore the old code for that function.
