Currently, there is no terminator entry for exynosautov920_cmu_of_match,
hence facing below KASAN warning,
BUG: KASAN: global-out-of-bounds in of_match_node+0x120/0x13c

The buggy address belongs to the variable:
exynosautov920_cmu_of_match+0xc8/0x2c80
Add a dummy terminator entry at the end to assist of_match_node() in
traversing up to the terminator entry without accessing an
out-of-boundary index.
