Add device-tree support for the following SoMs:
- Mercury SA1 (cyclone5)
- Mercury+ SA2 (cyclone5)
- Mercury+ AA1 (arria10)

Further add device-tree support for the corresponding carrier boards:
- Mercury+ PE1
- Mercury+ PE3
- Mercury+ ST1

Finally, provide generic support for combinations of the above with
one of the boot-modes
- SD
- eMMC
- QSPI

All of the above can be freely combined. Combinations are covered by
the provided .dts files. This makes an already existing .dts file
obsolete. Further minor fixes of the dtbs_checks are added separtely.

The current approach is also required  for corresponding bootloader
integration using dts/upstream. That's also one of the reasons for
the .dtsi split.

v4 -> v5:
- separate generic socfpga dt fixes from this patch set. The focus of this
  patch set is the dts/dtsi files and related bindings, not additional
  intel/socfpga refactoring

v3 -> v4:
- add separate patch to match "snps,dwmac" compatible in corresponding
  driver, required by binding check
- replace non-standard node names in .dtsi files by node names recommended
  by the device tree standard v0.4

v2 -> v3:
- dropped the patch to add the socfpga clock bindings:
  Documentation/devicetree/bindings/clock/altr,socfpga-a10.yaml
  reason: refactoring the "altr,socfpga-" TXT files to .yaml files is a
  different story involving several other files, thus can be part of a
  future patch series, not related to the current upstreaming the
  Enclustra DTS support, so dropped
- adjust comments on boot mode selection
- adjust titles to several bindings patches

v1 -> v2:
- split bindings and DT adjustments/additions
- add several fixes to the socfpga.dtsi and socfpga_arria10.dtsi where
  bindings did not match
- extend existing bindings by properties and nods from arria10 setup
- implement the clock binding altr,socfpga-a10.yaml based on existing
  text file, rudimentary datasheet study and requirements of the
  particular DT setup
