power: avs: qcom-cpr: add unspecified HAS_IOMEM dependency

Currently CONFIG_QCOM_CPR=y implicitly depends on CONFIG_HAS_IOMEM=y;
consequently, on architectures without IOMEM we get the following build
error:

/usr/bin/ld: drivers/power/avs/qcom-cpr.o: in function `cpr_probe':
drivers/power/avs/qcom-cpr.c:1690: undefined reference to `devm_ioremap_resource'

Fix the build error by adding the unspecified dependency.
