clk: qcom: clk-debug: Add bandwidth voting for MM clock measures

Due to a new requirement to disconnect configuration space for
multimedia clients when MMCX is power collapsed, the debug driver
needs to reconnect the ports before trying to access any of the
multimedia config slaves. Add bandwidth voting before attempting
to access any of the MM clock controller to satisfy this requirement.
