Add support for UHS-I modes by adding voltage regulator device tree nodes and corresponding pinmux details, to power cycle and voltage switch cards. Set respective tags in sdhci0 and remove no-1-8-v tag from sdhci1 device tree nodes. Also update the delay values for various speed modes supported, based on the revised january 2021 J7200 datasheet[2].
