[PATCH] clocksource: stm32: introduce dependency on HAS_IOMEM

[Nicolai Stange]

Fix allmodconfig compilation failer for ARCH=um:
  drivers/clocksource/timer-stm32.c: In function 'stm32_clockevent_init':
  drivers/clocksource/timer-stm32.c:175:2:
    error: implicit declaration of function 'iounmap'
    [-Werror=implicit-function-declaration]
      iounmap(data->base);
      ^

Make CLKSRC_STM32 depend on HAS_IOMEM.

Drop this patch.

1cb6c2151850 ("clocksource: Increase dependencies of timer-stm32 to
               limit build wreckage")
from linux-next also fixes this, it introduces a dependency on ARM.

So, if you do not care about making the IOMEM dependency explicit,
forget about it.
