[LEDE-DEV] [PATCH 2/3] ag71xx: Remove ___cacheline_aligned from ring structs.

[Rosen Penev]

Qualcomm's struct members and inner workings of their driver are all different.
While this might make sense for their driver, it seems to hurt here. In
iperf3, i've seen inconsistent results including a drop of 100mbps on an
Archer C7v4. This patch keeps the results high and relatively consistent.
