Subject: [PATCH 01/20] pinctrl: pinctrl_register_mappings() shouldn't be __init

It may be common for pinctrl_register_mappings() to be used from __init
context, but there's no reason that additional mappings shouldn't be
added at a later point, e.g. if loading modules that add pin controllers
and their mapping tables.
