From: Arnd Bergmann <arnd@xxxxxxxx>
The newly added code causes a build failure when -Werror is set:
drivers/soc/qcom/spm.c:388:12: error: 'spm_get_cpu' defined but not used [-Werror=unused-function]
Remove the #ifdef and instead use an IS_ENABLED() check that lets the
compiler perform dead code elimination instead of the preprocessor.
Fixes: 6496dba142f4 ("soc: qcom: spm: add support for voltage regulator")
