[PATCH v2] thermal: Fix build error of missing devm_ioremap_resource on UM

[Krzysztof Kozlowski]

The devres.o gets linked if HAS_IOMEM is present so on ARCH=um
allyesconfig (COMPILE_TEST) failed on many files with:

drivers/built-in.o: In function `kirkwood_thermal_probe':
kirkwood_thermal.c:(.text+0x390a25): undefined reference to `devm_ioremap_resource'
drivers/built-in.o: In function `exynos_tmu_probe':
exynos_tmu.c:(.text+0x39246b): undefined reference to `devm_ioremap'

The users of devm_ioremap_resource() which are compile-testable should
depend on HAS_IOMEM.

Changes since v1:
1. Fix linking error also on TI.
2. Use different approach for HAS_IOMEM dependency. IT is needed only
   for COMPILE_TEST so use && to show that.
