ioremap has provided non-cached semantics by default since the Linux 2.6
days, so remove the additional ioremap_nocache interface.

The EDAC_DIMM_PTR() macro takes 3 arguments from struct mem_ctl_info.
Clean up this interface to only pass the mci struct and replace this
macro with a new function edac_get_dimm().
Also introduce an edac_get_dimm_by_index() function for later use.
This allows it to get a DIMM pointer only by a given index. This can
be useful if the DIMM's position within the layers of the memory
controller or the exact size of the layers are unknown.
Small style changes made for some hunks after applying the semantic
patch.
Semantic patch used:
@@ expression mci, a, b,c; @@
-EDAC_DIMM_PTR(mci->layers, mci->dimms, mci->n_layers, a, b, c)
+edac_get_dimm(mci, a, b, c)

Coffee Lake seems to work like Skylake and Kaby Lake. Add all device IDs
for Coffee Lake-S CPUs according to datasheet.

so rename it to edac_mc.h.

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.

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)
