drm/amdgpu: Add EEPROM I2C address support for ip discovery
1. Update EEPROM_I2C_MADDR_SMU_13_0_0 to EEPROM_I2C_MADDR_54H 2. Add EEPROM I2C address support for smu v13_0_0 and v13_0_10. Signed-off-by: Candice Li <candice.li@amd.com> Reviewed-by: Tao Zhou <tao.zhou1@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
