coreboot/fam15h: re-add kgpe-d16 and kcma-d8

also kfsn4-dre

this is still based on the old coreboot 4.11 version.

i have on todo to adapt dasharo coreboot for use in the master
branch of lbmk, for mainline libreboot releases.

since i'm doing c-libreboot for the GNU project, namely GNU Boot,
and since GNU Boot has dre/d8/d16 in their tree, re-add it here
for them.

i literally just copied this from them, who in turn copied it from
libreboot in an older revision anyway.

but there is one fix:

src/vendorcode/cavium/bdk/libbdk-hal/if/bdk-if-phy-vetesse.c

^ this blob wasn't being deleted by gnuboot, nor by libreboot
in the older revision that it forked from. an oversight. i decided
to audit the deblobbing and found this one was overlooked, out of
about 900 files picked up by deblob-check.

so this re-addition of dre/d8/d16 support is actually even better
deblobbed than gnuboot, or old-libreboot.
