[PATCH 1/1] thermal: Fix build error of missing devm_ioremap_resource on UM

[Talel Shenhar]

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

drivers/thermal/thermal_mmio.o:
In function 'thermal_mmio_probe':thermal_mmio.c:(.text+0xe1):
undefined reference to `devm_ioremap_resource'

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