x86/of: Move the x86_flattree_get_config() call out of x86_dtb_init()
Fetching the device tree configuration before initmem_init() is necessary
to allow the parsing of NUMA node information. However moving the entire
x86_dtb_init() call before initmem_init() is not correct as APIC/IO-APIC enumeration
has to be after initmem_init().
Thus, move the x86_flattree_get_config() call out of x86_dtb_init(),
into setup_arch(), to call it before initmem_init(), and
leave the ACPI/IOAPIC registration sequence as-is.
[ mingo: Updated the changelog for clarity. ]
