Subject: [PATCH v3 0/2] J7200: Add support for higher speed modes in MMCSD subsystems

The following series of patches 
- Add support for the zeroth instance of GPIO subsystem in the main domain
- 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 

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
