arm: K3: sysfw-loader: Add a config_pm_pre_callback()
System firmware does not guarantee that clocks going out of the device will be stable during power management configuration. There are some DCRC errors when SPL tries to get the next stage during eMMC boot after sysfw pm configuration. Therefore add a config_pm_pre_callback() to switch off the eMMC clock before power management and restart it after it is done.
