[PATCH v7 01/39] ARM: ep93xx: Add terminator to gpiod_lookup_table

From: Nikita Shubin <nikita.shubin at maquefel.me>

Without the terminator, if a con_id is passed to gpio_find() that
does not exist in the lookup table the function will not stop looping
correctly, and eventually cause an oops.

Fixes: b2e63555592f ("i2c: gpio: Convert to use descriptors")
