Make it possible to scale performance states of the power domain and
interconnect of the SPI QUP controller in relation to the selected SPI
speed / core clock. This is done separately by:
- Parsing the OPP table from the device tree for performance state
votes of the power domain
- Voting for the necessary bandwidth on the interconnect path to DRAM
