[PATCH 5/8] ARM: dts: imx50-kobo-aura: convert sd2_vmmc to regulator-fixed

[Frank.Li at oss.nxp.com]

From: Frank Li <Frank.Li at nxp.com>

The sd2_vmmc regulator was using compatible = "regulator-gpio" with
only a single state entry (states = <3300000 0>), which violates the
gpio-regulator DT schema that requires at least two state pairs.

Since the regulator operates at a fixed 3.3 V (regulator-min-microvolt
equals regulator-max-microvolt), convert the node to regulator-fixed.

Fix below check_dtbs warnings:
  arch/arm/boot/dts/nxp/imx/imx50-kobo-aura.dtb: gpio-regulator (regulator-gpio): states: [[3300000, 0]] is too short
