Old kernels are missing the definition of SET_SYSTEM_SLEEP_PM_OPS in linux/pm.h:
media_build/v4l/msp3400-driver.c:871:2: error: implicit declaration of function 'SET_SYSTEM_SLEEP_PM_OPS' [-Werror=implicit-function-declaration]
media_build/v4l/msp3400-driver.c:872:1: error: initializer element is not constant
media_build/v4l/msp3400-driver.c:872:1: error: (near initialization for 'msp3400_pm_ops.prepare')
Add it to compat.h to fix the compilation breakage.
