The following series of patches
- Add support for GPIO subsystem in main and wakeup domains.
- Add voltage regulator device tree nodes and their corresponding pinmux
  to support power cycle and voltage switch required for UHS-I modes
- sets respective tags in sdhci0 node to support higher speeds
- remove no-1-8-v tag from sdhci1 node to support UHS-I modes
- Update delay values for various speed modes supported.

Changes since v5:
- Corrected the link in patch 3 as it broken.
- Added the version number for the references used in patch 3.
- picked up reviewed-by from gyrgorii for patches 1 and 2.

Changes since v4:
- Added main_i2c0 pinmux required for doing power cycles to MMCSD1
  subsystem
- Updated delay values for various speed modes supported
- Corrected the ti,ngpio property to indicate highest gpio lines that
  can be accessed.
- Reran the performace tests

Changes since v3:
- Removed patch (1 in v3).
- Rebased and included patches that add support for GPIO from series [1].
- Re-ran the performace tests for SD and eMMC.

Changes since v2:
- Added main_gpio0 DT node
- Added voltage regulator device tree nodes required to support UHS-I modes

Changes since v1:
- squashed the two patches into one
- added performance logs for the above mentioned speed modes
