soc: qcom: rpmh-rsc: Include state in trace event

Browse Source 
When tracing messages written to the RSC it's very useful to know the
type of TCS being targeted, in particular if/when the code borrows a
WAKE TCS for ACTIVE votes.

Add the "state" of the message to the traced information.

While at it, drop the "send-msg:" substring, as this is already captured
by the trace event itself.
