The macro to generate a Bus Controller Manager (BCM) TCS command is used
by the interconnect driver but might also be interesting to other
drivers that need to construct TCS commands for sub processors so move
it out of the sdm845 specific file and into the header.

Unless this is supposed to be applied by me?

BTW, I wonder why we need an rpm clk driver much at all nowadays, except
maybe for the XO clk state. The big user, from what I can tell, is the
interconnect driver and we don't use any of the features of the clk
framework besides the API to set a frequency. Maybe it would be better
to just push push the bus frequency logic into interconnect code, then
XO clk is the only thing we need to keep, and it can be a simple on/off
thing.

There's been a number of cases where we'll need to enable the buffered
XOs, but perhaps these are handled by other subsystems these days(?)

If so the one case that remains would be the operation of explicitly
holding CXO enabled during operations such as booting the remoteprocs.
