x86: apic: Move probe_nr_irqs_gsi() into ioapic_init_mappings()

Browse Source 
probe_br_irqs_gsi() is called right after ioapic_init_mappings() and
there are no other users. Move it into ioapic_init_mappings() so the
declaration can disappear and the function can become static.

Rename ioapic_init_mappings() to ioapic_and_gsi_init() to reflect that
change.
