Add sysclk auto mode. When it's sysclk auto mode, if the MCLK is available for clock configure, using MCLK to provide sysclk directly, otherwise, search a available pll out frequcncy and set pll. Configure clock in hw_params may cause problems when using bypass style paths without hw_params in machine driver getting called. So add configure clock to set_bias_level.
