From: Laxman Dewangan <ldewangan-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Since of_device_id.data is declared as a pointer to const data a few
more consts can be added in this driver.

[ukl: split Laxman's patch to prevent warnings in the middle of the
series. Original patch was sent with msgid
1346217447-19730-1-git-send-email-ldewangan-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org]
