[PATCH v3 1/4] gpiolib: unify pr_* messages format

[Andy Shevchenko]

This patch includes the following amendments:
 1) use "?" as a label when the last one is not defined in gpiod_*;
 2) whenever it's possible gpiod_* are used;
 3) print a function name, if it's already used in other messages.

Additionally it fixes an indentation in few places.

[PATCH v3 2/4] gpiolib: introduce chip_* to print with chip->label prefix

[Andy Shevchenko]

In several places we are printing messages with prefix based on chip->label.
Introduced macros help us to do this easier and in uniform way.
