As said in commit f2c2cbcc35d4 ("powerpc: Use pr_warn instead of
pr_warning"), removing pr_warning so all logging messages use a
consistent <prefix>_warn style. Let's do it.

We have 3 identical copies of the ioapic domain ops for acpi, mpparse,
and sfi. Have a global one in the io_apic code and be done with it.
To avoid include hell in io_apic.h, create a private irqdomain header
and include the generic irqdomain header from there.

Convert IOAPIC driver to support and use hierarchical irqdomain
interfaces. It's a little big, but would break bisecting if we split
it into multiple patches.
Fold in a patch from Andy Shevchenko <andriy.shevchenko@linux.intel.com>
to make it bisectable.

Refine SFI to use common irqdomain map interface to program IOAPIC pins,
so we can unify the callsite to progam IOAPIC pins.

Enhance SFI to provide basic support of irqdomain with identity mapping
between GSIs and IRQs.
Some Intel MID platforms assumes identity mapping between GSI and IRQ,
so we can't dynamically allocate IRQ number on demand.

Enhance function mp_register_ioapic() to support irqdomain.
When registering IOAPIC, caller may provide callbacks and parameters
for creating irqdomain. The IOAPIC core will create irqdomain later
if caller has passed in corresponding parameters.

Found one x2apic pre-enabled system, x2apic_mode suddenly get
corrupted after register some cpus, when compiled
CONFIG_NR_CPUS=255 instead of 512.
It turns out that generic_processor_info() ==> phyid_set(apicid,
phys_cpu_present_map) causes the problem.
phys_cpu_present_map is sized by MAX_APICS bits, and pre-enabled
system some cpus have an apic id > 255.
The variable after phys_cpu_present_map may get corrupted
silently:
ffffffff828e8420 B phys_cpu_present_map
ffffffff828e8440 B apic_verbosity
ffffffff828e8444 B local_apic_timer_c2_ok
ffffffff828e8448 B disable_apic
ffffffff828e844c B x2apic_mode
ffffffff828e8450 B x2apic_disabled
ffffffff828e8454 B num_processors
...
Actually phys_cpu_present_map is referenced via apic id, instead
index. We should use MAX_LOCAL_APIC instead MAX_APICS.
For 64-bit it will be 32768 in all cases. BSS will increase by 4k bytes
on 64-bit:
text data bss dec filename
21696943 4193748 12787712 38678403 vmlinux.before
21696943 4193748 12791808 38682499 vmlinux.after
No change on 32bit.
Finally we can remove MAX_APCIS that was rather confusing.
