crypto: Make Open Firmware device id constant
From: Márton Németh <nm127@freemail.hu>
The match_table field of the struct of_device_id is constant in <linux/of_platform.h>
so it is worth to make the initialization data also constant.
The semantic match that finds this kind of pattern is as follows:
