Hello Paul Menzel, build bot (Jenkins), coreboot org,

Change subject: nb/intel/x4x/raminit: Rework receive enable calibration
......................................................................
nb/intel/x4x/raminit: Rework receive enable calibration
Moves receive enable calibration to a separate file to lighten
raminit.c a bit.
Receive enable calibration is quite similar to gm45 so it reuses some
of its function names.
The functional changes are:
* the minimum coarse is now reset for each channel;
* on the second fine search for DQS high, TAP overflow is handled by
increasing medium.
These might improve stability.
TESTED on ga-g41m-es2l
