restore_agesa.sh - restores the opensource AMD AGESA boards

restore_agesa.sh reverts the opensource AGESA AMD boards removal
that happened after 5e8e911b7caee021faff96c4e82a77a42544ea62
commit (0 point of history, or 0 PoH) - by git-reverting:
    1) the "bad commits" (marked as "CBF" = coreboot build failure)
       - that either remove or break a code needed for our boards
    2) the "unlucky commits" (marked as "GRF" = git revert failure)
       - that are a roadblock for git-reverting the "bad commits"

Right now at 88bc0f1604494de0f87c6954c050e7ef4d1c4457 (7153 PoH),
it takes 57 CBF git reverts - just 1% of 7153 commits since the
OSS AGESA removal! - making this removal look questionable and
the idea of opensource AGESA AMD boards restoration viable.

SUCCESSFUL BOOT TESTS for the opensource AGESA boards which I own
(Lenovo G505S - fam15 laptop, ASUS A88XM-E - fam15 desktop,
                              ASUS AM1I-A  - fam16 desktop) :
88bc0f1604494de0f87c6954c050e7ef4d1c4457 (7153 PoH) for Lenovo G505S
1879b6a34a6e93a93d691a0d9f2457d6251a17c1 (6092 PoH) for ASUS AM1I-A
1879b6a34a6e93a93d691a0d9f2457d6251a17c1 (6092 PoH) for ASUS A88XM-E
69ffebf5ccf123bc0b3fb28b485985af0597761d (3698 PoH) for ASUS A88XM-E

NOTE for A88XM-E and AM1I-A: may be a bootable USB detection problem
if you add too many floppy images (csb_patcher.sh) to a coreflop ROM
