Skylake adjusts some register locations, but otherwise follows the
existing model quite closely. I was able to verify that the 'ce_count'
increments when 'bad dimms' are used. The accounting of 'ce_count' and
'ue_count' is the primary functionality of interest for us. Tested on
Intel(R) Xeon(R) CPU E3-1260L v5 @ 2.90GHz.

These are not implementations of default architecture code but helpers
for drivers. Move them to the place they belong to.

Check for memory allocation and mchbar mapping failures before
initializing the dimm info tables needlessly.

Add a driver for the E3-1200 series of Intel DRAM controllers, based on
the following E3-1200 specs:
http://www.intel.com/content/www/us/en/processors/xeon/xeon-e3-1200-family-vol-2-datasheet.html
http://www.intel.com/content/www/us/en/processors/xeon/xeon-e3-1200v3-vol-2-datasheet.html
I've tested this on bad memory hardware, and observed correlating bad
reads and uncorrected memory errors as reported by the driver.
Tested against:
CPU E3-1270 v3 @ 3.50GHz : 8086:0c08 (haswell)
CPU E3-1270 V2 @ 3.50GHz : 8086:0158 (ivy bridge)
CPU E31270 @ 3.40GHz : 8086:0108 (sandy bridge)
