ARM: vexpress: use ARM_CPU_SUSPEND if needed
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. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Fixes: 3592d7e002438 ("ARM: 8082/1: TC2: test the MCPM loopback during boot") Acked-by: Nicolas Pitre <nico@linaro.org> Acked-by: Liviu Dudau <liviu.dudau@arm.com> Cc: Kevin Hilman <khilman@linaro.org> Cc: Sudeep Holla <sudeep.holla@arm.com> Cc: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>
