for 6.1, please pull the following:
 
 - Rafal improves the BCM5301X PCIe DT nodes schema validation by
 flagging the PCIe controller with a missing "device_type" property
 
 - William merges BCM4908 within BCMBCA since this chip is part of the
 Broadcom Broadband Carrier Access group and follows the architecture of
 those chips
