[U-Boot] [RFC PATCH v2 00/18] arm: socfpga: gen5: move to DM

[Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com>]

This is an RFC series with the target to move SPL code from arch to
DM drivers.

It is not finished, but I send this here for discussion mainly about
the devicetree format with the goal of keeping the various sub-
architectures (cyclone5, arria10, etc.) in the same style.

Patch 8 adds a C tool to convert existing gen5 qts handoff files to a
handoff dtsi. As an example, the last patch contains the handoff dtsi
for socfpga_socrates.

I have sent v1 some time ago, but this one has heavily changed and is
not finished, thus v2 but RFC. This series also is not edited to fix
patman warnings, yet.

Changes in v2:
- add dts based reset handling (messed up in v1)
- split this patch from v1 5/6
- split this patch from v1 5/6
