ARM: ep93xx: Add terminator to gpiod_lookup_table
stable inclusion
from stable-v5.10.211
commit 70d92abbe29692a3de8697ae082c60f2d21ab482
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2O0
CVE: CVE-2024-26751
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=70d92abbe29692a3de8697ae082c60f2d21ab482
--------------------------------
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.
