* Fix parsing in vpu_count on workstation SKX
* Document Skylake-X as Haswell for single FMA
* Update vpu_count for Skylake and Cascade Lake models
* Support printing the configuration selected, controlled by the environment
Intended particularly for diagnosing mis-selection of SKX through
unknown, or incorrect, number of VPUs.
* Move bli_log outside the cpp condition, and use it where intended
* Add Fixme comment (Skylake D)
* Mostly superficial edits to commits towards #351.
Details:
- Moved architecture/sub-config logging-related code from bli_cpuid.c
to bli_arch.c, tweaked names, and added more set/get layering.
- Tweaked log messages output from bli_cpuid_is_skx() in bli_cpuid.c.
- Content, whitespace changes to new bullet in HardwareSupport.md that
relates to single-VPU Skylake-Xs.
* Fix comment typos
