Add interconnect bandwidths for SDHC driver using OPP framework that is required by SDHC driver based on the clock frequency and bus width of the card. Otherwise, the system clocks may run at minimum clock speed and thus affecting the performance. This change is based on [1] [Patch v8] Introduce OPP bandwidth bindings (https://lkml.org/lkml/2020/5/12/493) [2] [Patch v3 09/17] mmc: sdhci-msm: Fix error handling for dev_pm_opp_of_add_table() (https://lkml.org/lkml/2020/5/5/491) [3] [RFC v6 2/2] dt-bindings: mmc: sdhci-msm: Add interconnect BW scaling strings (https://lkml.org/lkml/2020/3/23/409) as there were no extra changes made on [3], retaining the Acked-by and Reviewed-by sign-off from [3].
