Timur Kristóf ec917f19ff drm/amd/pm/smu7: Fix AC/DC switch notification ...

There were two mistakes in the previous implementation:

The check for AutomaticDCTransition should be inverted.
We recently learned that the kernel should send
PPSMC_MSG_RunningOnAC when the flag is set, and not the
other way around.

The clocks also need to be recomputed, because the code in
the smu7_apply_state_adjust_rules() function selects
different limits on AC and DC.
