nb/intel/sandybridge: Rename `read_training` function

Given that it sets the receive enable mode bit in the GDCRTRAININGMOD
register, it's clear that this is about receive enable calibration.

Remove a potentially-outdated comment. Proper documentation will be
written once code refactoring and various improvements are complete.
