I've got this working fine, I had to add 
BR2_PACKAGE_MURATA_CYW_FW_CYW43430 instead of 
BR2_PACKAGE_LINUX_FIRMWARE_BRCM_BCM43XXX as I mentioned before, I also 
added BR2_PACKAGE_WPA_SUPPLICANT_PASSPHRASE

and I've successfully connected with my wifi network.

Could you verify if it works well on your device?
