PM: sleep: Do not assume that "mem" is always present

An implementation of suspend_ops is allowed to reject the PM_SUSPEND_MEM
suspend type from its ->valid() callback, we should not assume that it
is always present as this is not a correct reflection of what a firmware
interface may support.

Fixes: 406e79385f32 ("PM / sleep: System sleep state selection interface rework")
