clk: qcom: clk-rpmh: Fix overflow in BCM vote

[ Upstream commit a4e5af27e6f6a8b0d14bc0d7eb04f4a6c7291586 ]

Valid frequencies may result in BCM votes that exceed the max HW value.
Set vote ceiling to BCM_TCS_CMD_VOTE_MASK to ensure the votes aren't
truncated, which can result in lower frequencies than desired.
