Timur Kristóf 86b6cf8387 drm/amd/pm/si: Fix AC/DC switch notification

There were two mistakes in the previous implementation:

The check for ATOM_PP_PLATFORM_CAP_HARDWAREDC 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 si_apply_state_adjust_rules() function selects different
limits on AC and DC.
