Some power management controllers need to support DTS and will use
the suspend interface thus this patch was to export such interface
for their use.

Hi, Yinbo,

I think this patch should go through the loongarch tree and the others
to go through the soc tree, so I just applied this one. The next
version you can only send the other two, thanks.
