atomic_orr() was introduced to this driver with

2014-03-06 5cbb9c285bdc brcmfmac: Use atomic functions for intstatus update. 

as it seems atomic_set_mask() was not available cross arch. And atomic_or() in
generic code was indeed introduced after that

2014-04-23 560cb12a4080 locking,arch: Rewrite generic atomic support 

Hence likely the reason author went with home grown atomic_orr()
