[v4] 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.

Signed-off-by: Anatolij Gustschin <agust@denx.de>
---
Changes in v4:
 - move stubs to gpio/machine.h

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

Thanks! What about this one https://lkml.org/lkml/2017/4/20/907 ?
Any issues with it? Or can it be queued for v4.13?

Thanks,

It was probably not sent to me (just to the mailing list?) or some
other hickup. I will try to find it min my mailbox.
