broadcom-sta: fixes for kernel version >= 3.18
This replaces our patches with those from Arch's package [1]. Further discussion can be found on the Arch forum [2]. This patch set is a superset of the previous set, and resolves the immediate and consistent kernel panics I've seen on my MacBook Pro Retina since switching from version 3.16 to 3.18 of the Linux kernel. Fixes #5315 Fixes #7710 1: https://aur.archlinux.org/packages/broadcom-wl/ 2: https://bbs.archlinux.org/viewtopic.php?id=192287
