Add a new apcb edit tool, apcb_v3a_edit.py, that injects SPDs into
an APCB for phoenix platform.
The tool makes several assumptions:
* Each SPD only uses blocks 0, 1, 3 and 5. All other blocks are zero.
* Each block is 64 bytes.
* Dimm and socket are always 0
* Unused SPD entries are zero'd

apcb_v3_edit.py tool edits APCB V3 binaries. Specifically it will inject
up to 16 SPDs into an existing APCB. The APCB must have a magic number
at the top of each SPD slot.

New util directories have been added with no description.md file.
The description file for supermicro was added at a secondary level,
which doesn't help a user find the util since no path was added. Move
it up to the top level.

Passing binary SPD files to apcb_edit can lead to an encoding error,
since the files were read in text mode. To fix this, read SPD files
always in binary mode and only decode them, when `--hex` is set.
Tested by comparing output files from the same SPDs in both, binary and
hex mode.

On the Picasso architecture, the PSP is responsible for setting up DRAM
before releasing the x86. The APCB (AGESA PSP Configuration Block)
contains multiple SPDs and the GPIO numbers used to select the correct
SPD. Since the source to build the APCBs is not public, it can't be
built as part of the coreboot build. To work around this problem, we use
a template APCB and inject the relevant information.
