drivers: qcom: Add BCM vote macro to header

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.
