This is mostly written from scratch and uses common spd ddr2 decode
functions.
This improves the following:
* This fixes incorrect CAS/Freq detection on DDR2;
* Fixes tRFC computation; tRFC == 78 is a valid timing which is
excluded and 0 ends up being used; (TESTED)
* Timings selection does not use loops;
* Removes ddr3 spd decode and is re-added in follow-up patches using
common ddr3 spd functions;
* Raminit would bail out if a dimm was unsupported, now in some cases it
just marks the dimm slot as empty;
* It dramatically reduces stack usage since it does not allocate 4
times 256 bytes to store full SPDs, amongs other unused things that
were stored in sysinfo;
* Reports when no dimms are present;
* Uses i2c block read to read SPD which is about 5 times faster than
bytewise read, with a fallback to smbus mode in case of failure,
which does seem to happen when the system is forcefully powered
off.
