Added DRTM parameters structure version check that as per the current released DRTM specification [1]. Mainly to cater below mentioned in the specification [1] section 3.12 - For a given DRTM major version number this structure will always be extended in a backwards compatible manner. [1]: https://developer.arm.com/documentation/den0113/a Change-Id: I9f312c7f9f20152c5d7e40a22b462c7fe8db70bc Signed-off-by: Manish V Badarkhe <Manish.Badarkhe@arm.com>
