Subject: [PATCH v2] 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.
Signed-off-by: Jordan Crouse <jcrouse@...eaurora.org>

Changes in v2:
- Replace a similar BCS_TCS_CMD macro in clk-rpmh.c with the generic one
