In of_get_regulation_constraints() it can clearly be seen that the
return value of of_map_mode() is assigned to a signed integer. This
is important because the first thing the regulator core does with this
value is to compare it to -EINVAL.
Let's fix the return type of all of the current of_map_mode()
functions. While we're at it, we'll remove one pointless "inline".
Fixes: 5e5e3a42c653 ("regulator: of: Add support for parsing initial and suspend modes")
