Subject: [PATCH v3 2/4] arm64: dts: qcom: sm8250: Add SDHCI2 sleep mode pinctrl

Add required pins for SDHCI2, so that the interface can work reliably.
This commit adds sleep_state setup to the SoC DTSI, as it is common for
all boards.

Signed-off-by: Konrad Dybcio <konrad.dybcio@...ainline.org>

Changes since v2:
- Only add sleep_state to the SoC DTSI
