[ Upstream commit 498ba2a8a2756694b6f3888857426dbc8a5e6b6c ]
When CONFIG_ARM_QCOM_SPM_CPUIDLE is y and CONFIG_MMU is not set, compiling errors are encountered as follows:
drivers/cpuidle/cpuidle-qcom-spm.o: In function `spm_dev_probe': cpuidle-qcom-spm.c:(.text+0x140): undefined reference to `cpu_resume_arm' cpuidle-qcom-spm.c:(.text+0x148): undefined reference to `cpu_resume_arm'
Note that cpu_resume_arm is defined when MMU is set. So, add dependency on MMU in ARM_QCOM_SPM_CPUIDLE configuration.
