Compulab boards use the same eeprom code, so move the eeprom related
code to live under board/compulab/common directory.
Also make several adjustments to eeprom functions namespace, so it will
be generic for compulab boards.

Currently the cm-t35 support code lives under board/cm_t35 directory.
Some of the code can be shared with other/future CompuLab boards,
so move the cm-t35 to live under board/compulab/cm_t35 directory.

Buffer the PCB revision to avoid multiple eeprom accesses
for the same data and print it as a part of board information.

Legacy eeprom layout represents the revision number syntactically
(i.e. revision 1.00 is written as 0x100). This is inconsistent with
the representation in newer layouts, where it is defined semantically
(i.e. 0x64).
This patch fixes the issue by replacing the syntactic representation
with the semantic one.

Non-legacy layouts have an extended revision field,
but only the first 2 bytes are the PCB revision.

Switch to the new EEPROM module and fix the problem of MAC address
being read from the wrong offset due to lack of distinction between
EEPROM layouts.
