pins: Explicitly pass can_invert and can_pullup to lookup_pin()

Browse source 
Don't pass pin_type to lookup_pin() - instead, if a pin can be
inverted or can have a pullup, then the caller must explicitly specify
that when calling lookup_pin().  This simplifies the code for the
cases where it is not valid to invert or pullup.

Explicitly pass the pin_type to setup_pin() and have ppins.setup_pin()
apply default pullup and invert flags.
