The vexpress tc2 power management code calls mcpm_loopback, which
is only available if ARM_CPU_SUSPEND is enabled, otherwise we
get a link error:
arch/arm/mach-vexpress/built-in.o: In function `tc2_pm_init':
arch/arm/mach-vexpress/tc2_pm.c:389: undefined reference to `mcpm_loopback'
This explicitly selects ARM_CPU_SUSPEND like other platforms that
need it.
