commit 6639990dbb25257eeb3df4d03e38e7d26c2484ab upstream.

The existing code only deals with S0 and S3, let's start adding S1 and S2.

No functional change.

commit 7a5974e035a6d496797547e4b469bc88938343c2 upstream.

We currently don't have a means to differentiate between S3, S4 and S5. Add definitions so that we have select different code paths depending on the target state in follow-up patches.

commit 58ecb11eab44dd5d64e35664ac4d62fecb6328f4 upstream.

The IMR was assumed to be preserved when suspending to S4 and S5 states, but community reports invalidate that assumption, the hardware seems to be powered off and the IMR memory content cleared.

Make sure regular boot with firmware download is used for S4 and S5.
