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.
