Angel Pons 7519ca42b5 nb/intel/sandybridge: Clarify command timing calculation ... Command timing is the absolute value of the most negative `pi_coding` value across all ranks, or zero if there are no negative values. Use the MAX() macro to ease proving that `cmd_delay` can never be negative, and then drop the always-false underflow check. The variable type for `cmd_delay` still needs to be signed because of the comparisons with `pi_coding`, which is a signed value. Using an unsigned type would result in undefined and also undesired behavior.
