[PATCH] arm64: dts: marvell: armada-3720: drop 'marvell,xenon-emmc' properties

[Gabor Juhos]

The 'marvell,xenon-emmc' property used in some device trees of Armada 3720
based boards is not documented. Due to this dtbs_check throws warnings:

  .../armada-3720-atlas-v5.dtb: mmc@d8000 (marvell,armada-3700-sdhci): Unevaluated properties are not allowed ('marvell,xenon-emmc' was unexpected)
  .../armada-3720-espressobin-emmc.dtb: mmc@d8000 (marvell,armada-3700-sdhci): Unevaluated properties are not allowed ('marvell,xenon-emmc' was unexpected)

Apart from the warnings, 'git grep' says that the property is used in
device trees only:

  $ git grep -n 'marvell,xenon-emmc'
  arch/arm64/boot/dts/marvell/armada-3720-atlas-v5.dts:85:        marvell,xenon-emmc;
  arch/arm64/boot/dts/marvell/armada-3720-espressobin.dtsi:81:    marvell,xenon-emmc;

Although handling of the property was there in an early version of
the 'sdhci-xenon' driver during the initial submission [1], but that
part has been removed in later versions.

Drop the property from the affected device trees due to the reasons
mentioned above.

No functional changes intended, compile tested only.
