Guillaume Ranquet 0b45bf1659 clocksource/drivers/timer-of: Check return value of of_iomap in timer_of_base_init() ...

[ Upstream commit 4467b8bad2401794fb89a0268c8c8257180bf60f ]

of_base->base can either be iomapped using of_io_request_and_map() or
of_iomap() depending whether or not an of_base->name has been set.

Thus check of_base->base against NULL as of_iomap() does not return a
PTR_ERR() in case of error.
