Bluetooth: bpa10x: Read revision information in setup stage
For debugging pruposes, read the revision string of the BPA-10x devices and print it. For example one of the latest devices respond with the string SNIF_102,BB930,02/01/18,10:37:56. < HCI Command: Vendor (0x3f|0x000e) plen 1 07 . > HCI Event: Command Complete (0x0e) plen 49 Vendor (0x3f|0x000e) ncmd 1 Status: Success (0x00) 53 4e 49 46 5f 31 30 32 2c 42 42 39 33 30 2c 30 SNIF_102,BB930,0 32 2f 30 31 2f 31 38 2c 31 30 3a 33 37 3a 35 36 2/01/18,10:37:56 00 00 00 00 00 00 00 00 00 00 00 00 00 .............
