The pointer dev is being assigned but is never used, hence it is
redundant and can be removed. Cleans up clang warnings:

drivers/pinctrl/ti/pinctrl-ti-iodelay.c:582:2: warning: Value stored
to 'dev' is never read
drivers/pinctrl/ti/pinctrl-ti-iodelay.c:701:2: warning: Value stored
to 'dev' is never read
