NVIDIA's Tegra210 Jetson platform (P2180) uses the following
components:
	MAX77620 as system PMIC.
	PCA9539 as I2C GPIO bus expander

Enable the configs for PCA9539 GPIOs and Interrupt support and
MAX77620 MFD/GPIO/Pincontrol/Regulators.

Changes from V1:
- Rebase change and added PCA also in the enable list.

Jetson-TX1 uses the Maxim MAX77620 as system Power management IC.
Add device node for the MAX77620 with following details:
- Add device max77620 with.
	- Add all pins configurations.
	- Configure FPS of the device.
	- Configure SD/DCDC and LDOs regulators.
- populate the bus expander on base board P2597.
- Populate all fixed voltage regulators controlled by GPIOs from Tegra,
  PMIC and bus expanders.

For the different details, jetson-CV device tree files are referred from
downstream.

Changes from V1:
- Rebase change and populated based on applied patches.
