cpuidle: Fix ARM_QCOM_SPM_CPUIDLE configuration

[ 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.
