broadcom-nvram-config: separate recipes to different chipsets

Upstream driver changes cause the driver to request firmware based on
the device ID (e.g. 4329, 4330).  This also applies to the nvram config
file.  Restructure the recipes and separate by chipset.

Modify conf/machine to use chipset-specific broadcom nvram packages

linux-firmware: add bbappend to modify firmware file names

Upstream changes to the brcmfmac driver require a change to the firmware
file names to match the devid and interface type of the Broadcom chipset.
This also makes it easier for one machine to support multiple chipets in
Yocto.

This patch has been changed to adapt to the linux-firmware version
used in Daisy branch which is based on an older version of linux-firmware
repository.
