x86, uv: add early detection of UV system types
Portions of the ACPI code needs to know if a system is a UV system prior
to genapic initialization. This patch adds a call early_acpi_boot_init()
so that the apic type is discovered earlier.
V2 of the patch adding fixes from Yinghai Lu.
Much cleaner and smaller.
