Currently MDCR_EL3 register value is same for all the worlds(Non-secure, Secure, Realm and Root). With this approach, features enable/disable settings remain same across all the worlds. This is not ideal as there must be flexibility in controlling feature as per the requirements for individual world. The patch addresses this by providing MDCR_EL3 a per world value. Features with identical values for all the worlds are grouped under ``manage_extensions_common`` API.
