In order to make it possible to restore from hibernation not only in Linux but
also in e.g. U-Boot, we have to use sh_dmae_{suspend|resume}() for the {freeze|
thaw|restore}() PM methods. It's handy to achieve this with SIMPLE_DEV_PM_OPS()
macro; since that macro doesn't do anything when CONFIG_PM_SLEEP is undefined,
we don't need to #define sh_dmae_{suspend|resume} NULL anymore but we'll have to
enclose sh_dmae_{suspend|resume}() into the new #ifdef...
