nb/intel/x4x: Refactor setting default dll settings

This patch pushes these large default delay tables to a different file
to reduce cluttering up the actual raminit source. While doing so it
also uses more but smaller arrays and also adds the respective default
delays for DDR3 which are not yet used in this patch.

This patch add a function to set the read DQS delays instead of just
programming magic values. (This will prove useful for DQS read
training)

To prepare for adding trainings on the delay values it stores these
default delays in the sysinfo struct to program those. Later when
trainings are implemented those trained values will be used instead of
these safe default values, via using the cached sysinfo in 'mrc'
cache.

TESTED on DG43GT (still works fine)
