Subject: [PATCH v3 0/3] arm64: dts: qcom: x1e80100: Describe SDCs and
 enable support on QCP

The X1E80100 has two SDHC controllers (called SDC2 and SDC4).
Describe both of them and enable the SDC2 on QCP. This brings
SD card support for the microSD port on QCP.

The SDC4 is described but there is no device outthere yet that makes
use of it, AFAIK.

Didn't include the SDC4 pins yet because there are some bindings
errors that need to be addressed, and since there is no HW that
actually uses it, we can describe them at a later stage.

Changes in v3:
- Reordered the default and sleep pinconfs. Also the bias and
  drive-strength properties. As per Konrad's suggestion.
- Link to v2: https://lore.kernel.org/r/20241014-x1e80100-qcp-sdhc-v2-0-868e70a825e0@linaro.org

Changes in v2:
- rebased on next-20241011
- dropped the bindings schema update patch
- dropped the sdhci-caps-mask properties from both
  controllers as SDR104/SDR50 are actually supported
- Link to v1: https://lore.kernel.org/r/20241008-x1e80100-qcp-sdhc-v1-0-dfef4c92ae31@linaro.org
