Subject: [PATCH v3] gpiolib: Add stubs for gpiod lookup table interface

Add stubs for gpiod_add_lookup_table() and gpiod_remove_lookup_table()
for the !GPIOLIB case to prevent build errors. Also add prototypes.

Signed-off-by: Anatolij Gustschin <agust@denx.de>
---
Changes in v3:
 - add stubs for !GPIOLIB case. Drop prototypes, these are
   already in gpio/machine.h

Changes in v2:
 - move gpiod_lookup_table out of #ifdef
