intel/gm45: Add more debug output to read/write training

Add debug output for the timing values of the edges found during
    read and write training.

Now, output for one DIMM of DDR3-1066 in a roda/rk9 looks like:

[...]
    Lower bound for byte lane 0 on channel 0: 0.0
    Upper bound for byte lane 0 on channel 0: 8.4
    Final timings for byte lane 0 on channel 0: 4.2
    Lower bound for byte lane 1 on channel 0: 0.0
    Upper bound for byte lane 1 on channel 0: 10.2
    Final timings for byte lane 1 on channel 0: 5.1
    Lower bound for byte lane 2 on channel 0: 0.0
    Upper bound for byte lane 2 on channel 0: 7.5
    Final timings for byte lane 2 on channel 0: 3.6
    Lower bound for byte lane 3 on channel 0: 0.0
    Upper bound for byte lane 3 on channel 0: 11.4
    Final timings for byte lane 3 on channel 0: 5.6
    Lower bound for byte lane 4 on channel 0: 0.0
    Upper bound for byte lane 4 on channel 0: 9.4
    Final timings for byte lane 4 on channel 0: 4.6
    Lower bound for byte lane 5 on channel 0: 0.0
    Upper bound for byte lane 5 on channel 0: 11.2
    Final timings for byte lane 5 on channel 0: 5.5
    Lower bound for byte lane 6 on channel 0: 0.0
    Upper bound for byte lane 6 on channel 0: 8.4
    Final timings for byte lane 6 on channel 0: 4.2
    Lower bound for byte lane 7 on channel 0: 0.0
    Upper bound for byte lane 7 on channel 0: 10.4
    Final timings for byte lane 7 on channel 0: 5.2
    Lower bound for group 0 on channel 0: 1.7.5
    Upper bound for group 0 on channel 0: 2.2.2
    Final timings for group 0 on channel 0: 1.10.7
    Lower bound for group 1 on channel 0: 1.6.1
    Upper bound for group 1 on channel 0: 2.0.2
    Final timings for group 1 on channel 0: 1.9.1
    Lower bound for group 2 on channel 0: 2.0.7
    Upper bound for group 2 on channel 0: 2.8.1
    Final timings for group 2 on channel 0: 2.4.4
    Lower bound for group 3 on channel 0: 2.4.7
    Upper bound for group 3 on channel 0: 3.0.0
    Final timings for group 3 on channel 0: 2.8.3
    [...]

Final timings are always the average of the two bounds. The last dots
    separate eights (not decimals) and the middles are elenvenths or twelfths
    depending on the clock speed (twelfths in this case).
