arm64: dts: imx95-tqma9596sa-mb-smarc-2.dts: improve SD reset pulse
SD card spec says that at least 1 msec of power cut is needed
to reset an SD card. This is needed to get out of UHS-I mode.
In fact this pulse length alone is far too short in real world
environment due to capacitance etc. Implement a longer pulse using
regulator settings: 200 msec as working for other SoM using MB-SMARC-2.
