[PATCH] ARM: qcom: select ARM_CPU_SUSPEND for power management

[Arnd Bergmann]

The qcom spm driver uses cpu_resume_arm(), which is not included
in the kernel in all configurations:

drivers/built-in.o: In function `qcom_cpu_spc':
:(.text+0xbc022): undefined reference to `cpu_suspend'
drivers/built-in.o: In function `qcom_cpuidle_init':
:(.init.text+0x610c): undefined reference to `cpu_resume_arm'

This adds a 'select' Kconfig statement to ensure it's always
enabled.

This has been broken for a while but not even shown up in many thousands of
randconfig builds until today. Please queue it up for 4.5 unless you think
it should really go into 4.4 as well.
