CVE-2025-38272

net: dsa: b53: do not enable EEE on bcm63xx

In the Linux kernel, the following vulnerability has been resolved:

net: dsa: b53: do not enable EEE on bcm63xx

BCM63xx internal switches do not support EEE, but provide multiple RGMII
ports where external PHYs may be connected. If one of these PHYs are EEE
capable, we may try to enable EEE for the MACs, which then hangs the
system on access of the (non-existent) EEE registers.

Fix this by checking if the switch actually supports EEE before
attempting to configure it.
