Only core revisions older than 4 use BGMAC_CMDCFG_SR_REV0. This mainly
fixes support for BCM4708A0KF SoCs with Ethernet core rev 5 (it means
only some devices as most of BCM4708A0KF-s got core rev 4).
This was tested for regressions on BCM47094 which doesn't seem to care
which bit gets used.

If it's OK for everyone, I suggest taking this patch into net.git repo.
It obviously can't regress old devices and was well tested on new ones
by OpenWrt users.
