Refactor the FSP log level control by introducing a helper function
`fsp_set_debug_level()` to set the serial and MRC debug levels.
This change improves code readability and maintainability by separating
the log level setting logic from the main control flow. It also adds a
check to ensure the configured log levels are valid.
