nb/intel/sandybridge: Rename and refactor `discover_timC_write`

This is actually aggressive write training, similar to aggressive read
training. Rename it accordingly and refactor it to improve clarity.

Enabling IOSAV_n_SPECIAL_COMMAND_ADDR optimizations must only be done
for later Ivy Bridge steppings. Therefore, guard the code accordingly.
