minerva: update to v1.4
- Correct Zqlatch period checks - Update periodic training - Simplify some logic - Fix some mr13 values - Separate EMC channel enums from macros - Add extra reg flushes - Fix tree margin comparison signedness By using incorrect signedness on tree margins the delta taps would always apply. By casting margins to integer it now properly checks if it should apply delta taps on the new trimmers. This fixes a bug that exists in every Nvidia emc dvfs code.
