Subject: [PATCH] Adjust the registration method of PCIe and INET drivers, and
 set raid6_select to start asynchronously by default.

Asynchronous modules should now be configured in the DTS file, with an additional variable in the bootargs.
The recommended configuration is as follows:
driver_async_probe=spacemit-hdmi-drv,i2c-spacemit-k1x,ri2c-spacemit-k1x,k1xccic,sdhci-spacemit,k1x-dwc-pcie,pxa2xx-uart
