Luflosi 106d3fec43 framework AMD 7040: work around white screen / flickering issue on newer kernels
Fixes #817.

Updating the kernel if it is too old is already done by `common/cpu/amd/raphael/igpu.nix`, so I removed the redundant code.

Stop the system waking from suspend when the AC is plugged
in. The catch: it also disables waking from the keyboard.
