[PATCH] pwm: clps711x: add CONFIG_HAS_IOMEM dependence

[David Cohen]

clps711x uses io memory which makes it not compilable on architectures
without HAS_IOMEM such as UML:

drivers/built-in.o: In function `clps711x_pwm_probe':
pwm-clps711x.c:(.text+0x2848): undefined reference to
`devm_ioremap_resource'
