MHI fixes for v5.18

Couple of patches fixing the hibernation issue seen on MHI endpoint devices like
SDX65 modems:

- During hibernation, the host puts the device into D3cold after thaw() stage.
But at that time, the device would be in M0 state. So the device emits a
warning (not visible to the host but to device firmware only) stating invalid
transition. This is fixed by adding a poweroff() callback that puts the device
into M3 before D3cold.

- There is a possibility that the recovery worker might be running while trying
to powerdown the device. So flush the recovery worker before that.
