550fe4f198 x86/Voyager: remove X86_FIND_SMP_CONFIG Kconfig quirk
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.

f095df0a0c x86/Voyager: remove X86_BIOS_REBOOT Kconfig quirk
Voyager has this Kconfig quirk:

config X86_BIOS_REBOOT
	bool
	depends on !X86_VOYAGER
	default y

Voyager should use the existing machine_ops.emergency_restart reboot
quirk mechanism instead of a build-time quirk.

23394d1c93 x86/Voyager: remove X86_HT Kconfig quirk
Voyager has this Kconfig quirk:

	depends on (X86_32 && !X86_VOYAGER) || X86_64

That is unnecessary as HT support is CPUID driven and explicitly
 enumerated.

c0b5842a45 x86: generalize boot_cpu_id
x86/Voyager can boot on non-zero processors. While that can probably
be fixed by properly remapping the physical CPU IDs, keep boot_cpu_id
for now for easier transition - and expand it to all of x86.

3e5095d152 x86: replace CONFIG_X86_SMP with CONFIG_SMP
The x86/Voyager subarch used to have this distinction between
 'x86 SMP support' and 'Voyager SMP support':

 config X86_SMP
	bool
	depends on SMP && ((X86_32 && !X86_VOYAGER) || X86_64)

This is a pointless distinction - Voyager can (and already does) use
smp_ops to implement various SMP quirks it has - and it can be extended
more to cover all the specialities of Voyager.

So remove this complication in the Kconfig space.

Voyager has this Kconfig quirk for suspend/resume:

 config ARCH_SUSPEND_POSSIBLE
 	def_bool y

The proper mechanism to not suspend on a piece of hardware to disable
CONFIG_SUSPEND. Remove the quirk.

Voyager has this hibernation quirk:

 config ARCH_HIBERNATION_POSSIBLE

Hibernation is a generic facility provided on all x86 platforms. If it
is buggy on Voyager then that bug should be fixed - not worked around.

 	select HAVE_KVM if ((X86_32 && !X86_VOYAGER && !X86_VISWS && !X86_NUMAQ) || X86_64)

This is unnecessary, as KVM cleanly detects based on CPUID capabilities.

61b8172e57 x86: disable Voyager temporarily
x86/Voyager does not build right now and it's unclear whether it will
be cleaned up and ported to the subarch-less 32-bit x86 code - so disable
it for now.

If it's fixed we'll re-enable it - or remove it after some time. There's
a very low number of systems running development kernels on x86/Voyager
currently. (one or two on the whole planet)
