[v2] arm64: dts: qcom: sm6115: Move SDHC node(s)'s 'pinctrl' properties to dts

  Normally the 'pinctrl' properties of a SDHC controller and the
chip detect pin settings are dependent on the type of the slots
(for e.g uSD card slot), regulators and GPIO(s) available on the
board(s).

So, move the same from the sm6115 dtsi file to the respective
board file(s).

So, file or files? :D

This should have been

pinctrl-n
pinctrl-names

I made a mistake in my lenovo dts if that was your reference..

You should also mention that the implicit removal of sdhci1's
gpio properties from the lenovo j606f and oneplus billie2 is intentional
as they both use UFS instead of eMMC.

And one more thing, you missed bringing the CD pin back into pinctrl-0/1
in the tab dts. I'd really appreciate if you could fix up that ordering
mess I mentioned above while at it.

Not sure if I still stand by this...

IMO we should keep the default sdc1_on/off_state in sdhci1 and sdhci2.
That node is disabled anyway.  Only removable sdhci's need the pinctrl
extended with the CD pin (and whether that's done with a new pinctrl
node, or by adding the pin to &sdcX_on/off_state varies per SoC).  I
mentioned this in:

https://lore.kernel.org/linux-arm-msm/48607619-3a7b-a9d7-1e6a-c24f52539671@linaro.org/

But no-one gave their opinion.

In other words: it seems odd to define the sdcX_on/off_state in SoC DTS,
but then always require the board DTS to wire it up to the specific
sdhc_X node (when that is only needed when extending pinctrl-X with an
extra CD state).

In other words, IMO this should stay:
- if it is not used for a removable card, this is adequate
  (only boards with a removable card on sdhc1 would have to update these
  properties or the referenced pinctrl state with CD pin);
- the node is disabled by default anyway.

And we could keep this for exactly the same reason.
