[PATCH] ARM: at91: select CONFIG_ARM_CPU_SUSPEND

[Arnd Bergmann]

The reference to cpu_resume requires the corresponding
generic code to be enabled when CONFIG_PM is set:

arch/arm/mach-at91/pm.o: In function `sama5d2_pm_init':
pm.c:(.init.text+0x5e8): undefined reference to `cpu_resume'

Fixes: 24a0f5c539f9 ("ARM: at91: pm: Add sama5d2 backup mode")
