Subject: [PATCH 07/10] arm64: dts: qcom: sm6350-lena: Provide power to SDHCI 2 (SDCard slot)

Without power the SDCard slot / hardware remains dormant.

Like many other platforms these regulators are used exclusively by
SDHCI, and have their maximum voltage decreased to what downstream sets
on the consumer side.  Additionally the SDHCI driver supports setting a
load, for which the regulator definition is extended much the same.
