CVE-2026-68400

firmware: arm_ffa: Fix Endpoint Memory Access Descriptor offset calculation

In the Linux kernel, the following vulnerability has been resolved:

firmware: arm_ffa: Fix Endpoint Memory Access Descriptor offset calculation

Use the descriptor's `ep_mem_offset` to calculate the start of the endpoint
memory access array and to comply with the FF-A spec instead of defaulting
to `sizeof(struct ffa_mem_region)`.
This requires moving `ffa_mem_region_additional_setup()` earlier in the setup
flow.
Also, add sanity checks to ensure the calculated descriptor offsets do not
exceed `max_fragsize`.
