Set MACB_CAPS_EEE for the Raspberry Pi 5 RP1 southbridge (Cadence GEM_GXL rev 0x00070109 paired with BCM54213PE PHY). EEE has been verified on RP1 hardware: the LPI counter registers at 0x270-0x27c return valid data, the TXLPIEN bit in NCR (bit 19) controls LPI transmission correctly, and ethtool --show-eee reports the negotiated state after link-up. Other GEM variants that share the same LPI register layout (SAMA5D2, SAME70, PIC32CZ) can be enabled by adding MACB_CAPS_EEE to their respective config entries once tested.
