drm/amd/display: Reset DMUB mailbox SW state after HW reset
[Why]
Otherwise we can be out of sync with what's in the hardware, leading
to us rerunning every command that's presently in the ringbuffer.
[How]
Reset software state for the mailboxes in hw_reset callback.
This is already done as part of the mailbox init in hw_init, but we
do need to remember to reset the last cached wptr value as well here.
