* Adjust the PSRAM clock when over/underclock F_SYS Fixes #2818 * Need to increase PSRAM divider before sysclk increase Per datasheet, when increasing sysclk speed we need to set the qmi clocks first and do a dummy transfer to ensure no invalid speed operations happen on the bus. Handle the logic for this while setting up the overclock.
