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
performance test logs using EXT4 filesystem
- For eMMC HS400 speed mode,

- For SD SDR104 speed mode,

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
