src/poky:linux-firmware: split ath10k firmwares in separate packages

This patch introduces the following packages for ath10k based chips:

- linux-firmware-ath10k-qca4019
- linux-firmware-ath10k-qca6174
- linux-firmware-ath10k-qca9377
- linux-firmware-ath10k-qca9887
- linux-firmware-ath10k-qca9888
- linux-firmware-ath10k-qca988x
- linux-firmware-ath10k-qca9984
- linux-firmware-ath10k-qca99x0
- linux-firmware-ath10k-misc: catches all firmwares that are not
  already included in the other -ath10k- packages (currently empty).

linux-firmware-ath10k is now a meta package that depends on all of the
split-out ath10k packages.
