Talos-2: bring changes to a working state outside of usage of GPG key material backup as of now

- Closes #1452
- coreboot: Take Talos II 0.7 release coreboot config file that was inside of cbfs and use it as a base upstream.
- linux: Readd sysctl and proc requirements for cbmem to work.

TODO: fix gpg2 module so that the following doesn't happen (a ppc64 thing. Can't figure out why):

```
Adding generated key to current firmware and re-flashing...

Initializing Flash Programmer
Reading old flash contents. Please wait...
Flashing: [##################################################\] (100%)
Verifying flash contents. Please wait...
The flash contents were verified and the image was flashed correctly.

gpg: error running '//bin/dirmngr': probably not installed
gpg: failed to start dirmngr '//bin/dirmngr': Configuration error
gpg: can't connect to the dirmngr: Configuration error
gpg: no default secret key: No dirmngr
gpg: signing failed: No dirmngr
```
dirmngr is deactivated per configure statement --disable-dirmngr, and works as expected on x86
