Commit 72daceb9a10a ("net: rfkill: gpio: Add default GPIO driver mappings
for ACPI") removed possibility to request GPIO by table index for non-ACPI
platforms without changing it users. As result "shutdown" GPIO request
will fail if request for "reset" GPIO succeeded or "reset" will be
requested instead of "shutdown" if "reset" wasn't defined. Fix it by
making gpiod_lookup_table use con_id's instead of indexes.

beside a small typo in the commit message (is users -> its users) this looks 
good now. I can confirm that the gpio's are all available now.

I thing this should go through the tegra-soc tree. Thierry? Stephen?
