target/openrisc: Remove duplicate features property
The features property has stored the exact same thing as the cpucfgr spr. Remove the feature enum and property as it is not needed. In order to preserve the behavior or keeping features accross reset this patch moves cpucfgr into the non reset region of the state struct. Since the cpucfgr is read only this means we only need to sset cpucfgr once during class init. Signed-off-by: Stafford Horne <shorne@gmail.com>
