feat(drtm): update drtm setup function
Updated DRTM setup functionality that mainly does below 2 things
1. Initialise the DRTM DMA protection, this function assumes the
platform must support complete DMA protection.
2. Initialise the Crypto module that will be useful to calculate
the hash of various DRTM element involved.
