6.12-stable review patch. If anyone has any objections, please let me know.

From: Russell King (Oracle) rmk+kernel@armlinux.org.uk
commit c86692fc2cb77d94dd8c166c2b9017f196d02a84 upstream.
Implement the .support_eee() method to indicate that EEE is not supported by two switch variants, rather than making these checks in the .set_mac_eee() and .get_mac_eee() methods.
