Jiaxun Yang	68557c59a5	MIPS: Loongson64: Implement PM suspend for LEFI firmware ... Implement PM suspend for LEFI firmware. Entering STR (Suspend to RAM) is as simple as save our context then go to a firmware vector. Wake is a little bit treaky as we need to setup some CP0 status first, which can be done with smp_slave_setup.
