Combine Broadwell Chromeboxes using variant board scheme

Combine existing boards google/guado, rikku, and tidus using
    their common reference board google/jecht as a base.

Additional changes besides simple consolidation include:
     - simplify power LED functions
     - simplify HDA verb definitions using azelia macros
     - use common SoC functions to generate FADT table
     - correct FADT table header version
     - remove unused haswell_pci_irqs.asl
     - remove unused header includes (various)
     - set sane default fan speed (0x4d) for all variants

Variant setup modeled after google/beltino
