This Pull Request adds support for using the HPDC in OpenPiton. To do so, I have added and updated the L1.5 adapters and hpdcache cache subsystems.

Because previously the L1.5 interface types & enums were in the wt_cache pkg and adapter files, I have moved the typedefs to a l15_pkg provided by openpiton. This allows any cache (and any core) to interface with the L1.5.

The changes are working as tested in OpenPiton.

Hi @ArnauBigas. Could you investigate the failure? It could relate to an expired authentication token (as in actions/checkout#664)

Hi @ArnauBigas. Could you investigate the failure? It could relate to an expired authentication token (as in actions/checkout#664)

Hi, I am unsure why this is happening. The issue you link seems to be related as to when you use an authentication token to access a repository with special permissions, e.g. when cloning a private repository. I don't use any authentication token anywhere, and I wouldn't know where to upload this token. So I don't really know what's going on. I also can't seem to re-run the CI to check this, sorry I'm not used to github's actions 😓

Yes, I will shortly update this PR. Sorry, I have been on vacation for a while and have not had time to fix it before.
