Subject: [PATCH 096/114] 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.
