[PATCH v2 2/3] xen/x86: ioapic: Rename init_ioapic_mappings() to ioapic_init()

[Julien Grall <julien@xen.org>]

From: Julien Grall <jgrall@amazon.com>

The function init_ioapic_mappings() is doing more than initialization
mappings. It is also initialization the number of IRQs/GSIs supported.

So rename the function to ioapic_init().
