This series bumps WILC1000/3000 firmware to the latest available from
Microchip, updates existing defconfig files to include both WILC1000
and WILC3000 blobs, and adds a package to build the wilc driver as
an external kernel module.

The previous wilc1000-firmware package was extremely outdated, no longer
available on github, and installed the firmware files to the wrong
location for the current upstream kernel wilc1000 driver and Microchip's
separately maintained driver.

Since the firmware change includes individual WILC1000 and WILC3000
config options, this package is renamed to wilc-firmware.

The defconfigs of all platforms that used WILC1000 firmware were
touched to also include WILC3000 firmware. They either natively
have WILC3000 or can support either WILC1000/WILC3000 being connected
to these platforms.

I've attempted to test the firmware changes against
microchip_sama5d27_wlsom1_ek_mmc_dev_defconfig as this is a board I
have in my possession. However, the defconfig appears broken (Microchip
now maintains the evk in their own BR2_EXTERNAL repo):

The firmware and driver changes have been thoroughly tested, however,
on an embeddedTS platform (BR patch for this in the future, waiting on
kernel accepting FDT) that includes the WILC3000 device. We have a number
of platforms that all use this same device and are starting to push for
better upstream support overall. So this patch series is us laying the
groundwork for that.

Changes v1 -> v2:
	- Add un-prompted BR2_PACKAGE_WILC_FIRMWARE symbol to ensure that
	  wilc-firmware is built as part of make
	- Fix check-patch warning in wilc-firmware
	- Add wilc-firmware license copied Microchip's buildroot-external repo
	- Bump wilc-driver to linux4microchip-2021.10-1, removes kernel version
	  check that doesn't need to be there yet.

Kris Bahnsen (4):
  package/wilc1000-firmware: bump to 15.6
  package/wilc-firmware: rename from wilc1000-firmware
  configs: add WILC3000_FIRMWARE to compatible devices
  package/wilc-driver: new package
