2020-11-22nb/intel/sandybridge: Clean up COMPOFST1 logicAngel Pons
This register needs to be updated differently depending on the CPU generation and stepping. Handle this as per reference code. Further, introduce a bitfield for the register to make the code easier to read.

2020-11-22nb/intel/sandybridge: Correct get_COMP2 functionAngel Pons
Values differ between Sandy and Ivy Bridge. Remove the lookup table, since it contains duplicated values and is hard to see which values correspond to which frequencies.

2020-11-22nb/intel/sandybridge: Rename and refactor `discover_timC_write`Angel Pons
This is actually aggressive write training, similar to aggressive read training. Rename it accordingly and refactor it to improve clarity. Enabling IOSAV_n_SPECIAL_COMMAND_ADDR optimizations must only be done for later Ivy Bridge steppings. Therefore, guard the code accordingly.

When memory is running at fast frequencies, power-down modes can lessen system stability. Check tXP and tXPDLL values and use safer power down modes if their values are high. Do not use APD with DLL-off on mobile: vendor firmware does not use it, and it can influence system stability.

2020-11-22nb/intel/sandybridge: Use one sequence for write levelingAngel Pons
In order to run a write leveling test, one needs to unset the Qoff bit in MR1, then run the test, and finally set Qoff again. The current IOSAV sequence uses two subsequences to perform the test, while the other two are unused. It is possible to perform the two necessary MR1 updates in the same sequence, which can potentially improve runtime (not measured). Since `write_mrreg` is no longer used, it is necessary to handle address mirroring explicitly. This can be accomplished with the recently-added `ddr3_mirror_mrreg` function, which is also used in `write_mrreg`. Tested on Asus P8H61-M PRO, still boots.

2020-11-19nb/intel/sandybridge: Use arrays to program IOSAVAngel Pons

Since the number of subsequences is now known in advance, handling of global state can be simplified, which allows reusing the last sequence.
