Add mp_find_ioapic_pin() to find an IO APIC's specific pin from a GSI,
and use this function within acpi/boot. Make it non-static so other
code can use it too.

Impact: find right nr_irqs_gsi on some systems.
One test-system has gap between gsi's:
[ 0.000000] ACPI: IOAPIC (id[0x04] address[0xfec00000] gsi_base[0])
[ 0.000000] IOAPIC[0]: apic_id 4, version 0, address 0xfec00000, GSI 0-23
[ 0.000000] ACPI: IOAPIC (id[0x05] address[0xfeafd000] gsi_base[48])
[ 0.000000] IOAPIC[1]: apic_id 5, version 0, address 0xfeafd000, GSI 48-54
[ 0.000000] ACPI: IOAPIC (id[0x06] address[0xfeafc000] gsi_base[56])
[ 0.000000] IOAPIC[2]: apic_id 6, version 0, address 0xfeafc000, GSI 56-62
...
[ 0.000000] nr_irqs_gsi: 38
So nr_irqs_gsi is not right. some irq for MSI will overwrite with io_apic.
need to get that with acpi_probe_gsi when acpi io_apic is used

x86/Voyager had this Kconfig quirk:
config X86_FIND_SMP_CONFIG
def_bool y
depends on X86_MPPARSE || X86_VOYAGER
Which splits off the find_smp_config() callback into a build-time quirk.
Voyager should use the existing x86_quirks.mach_find_smp_config() callback
to introduce SMP-config quirks. NUMAQ-32 and VISWS already use this.

Impact: cleanup, avoid sparse warning
In asm/mpspec.h moved out pic_mode from CONFIG_X86_32 as it is common
for both 32 and 64 bit.
Fixes this sparse warning for x86_64:
arch/x86/kernel/apic.c:128:5: warning: symbol 'pic_mode' was not declared. Should it be static?

Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:
a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.
