[aur-general] Merge request: broadcom-wl-dkms, wireless-bcm43142-dkms, broadcom-wl6-dkms

[Frank Vanderham]

To clean up the naming and confusion around the various DKMS Broadcom
drivers out on AUR, please perform the following:

* merge the comments, history, etc. from wireless-bcm43142-dkms into
broadcom-wl-dkms
* merge the comments, history from broadcom-wl6-dkms into broadcom-wl-dkms

This means that those three packages should now be just one:
broadcom-wl-dkms. The current PKGBUILD of broadcom-wl-dkms is already the
latest, so going forward that is the maintained version.

Thanks!
