To be clear the "riscv: dts: starfive: jh7110-common: fix jh7110 SoC
boot from SD-card." commit does not affect Linux whatsoever, there is no
problem to boot Linux from SD Card impacted by having or not having this
commit. This also is not common, so should not be in jh7110-common, as
more JH-7110 SoC products by-the-numbers have transistor logic replacing
this signal selection to the StarFive loader in BootROM and so
precluding this from functioning.

This ignores the wider discussion about StarFive both deprecating this
capability (for Secondary Program Loader i.e. U-Boot SPL) of StarFive
Loader in JH-7110 BootROM loading from SD Card being deprecated
officially in the latest StarFive JH-7110 Technical Reference Manual and
StarFive JH-7110 Boot User Guide documentation, and the ongoing GPL
non-compliance by StarFive for use of GPL 2.0+ code in the JH-7110
BootROM; the latter being important if we want to accurately attempt to
support this deprecated feature set as a community (even when ignoring
for the moment this copyright license non-compliance).

I have done an ~80%+ analysis on Ghidra decompilation of the JH-7110
BootROM, and openly invite anyone that would like to help get this
effort to 100% is welcome to so that we may publish and refer to this
for technical competence. I do not object to the community supporting
this deprecated capability if there is any real documentation not based
on rumors and memes; but no one has offered to do take a moment to do
this most basic of fact finding. Evidently the StarFive maintainer(s)
have refused to support this, GPL non-compliance persists and only a
rough description from Hal has been written to the U-Boot developer mail
list that does not match my analysis, all while complaining about the
capability not being supported going forward.

I object to this PR it is NAK from me on the basis of stuffing this in
sideways without technical justification or review. Also I do object to
"riscv: dts: starfive: Milk-V Mars CM Lite broken-cd" as this goes the
wrong way around, it does not describe the hardware; if some external
carrier boards cannot deal with the capability of the Mars CM
system-on-module having card detect line then that should be dealt with
as a dtbo per-carrier board and not be replaced in the dts by a
broken-cd, although at least we had this discussion and Conor made a
decision with all the facts and discussion available.
