[TF-M] [RFC] Platform data adjustment

Hi,

I have created a couple of patches to change the way to assemble the partitions, and start with the platform data: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/8288

The basic idea is we would avoid using pointer to link data between partitions, as mentioned in one of the past tech forum topics: https://www.trustedfirmware.org/docs/TF-M_partition_storage_arrangement.pdf

Please help to review this patch, especially the platform owners, as this change modifies almost all platform sources.

Also, I just use a direct 'find and replace' so some of the copyright years are not updated. Would update them in subsequent small patches.

Thanks.
