[U-Boot] [PATCH 0/6] reset: add reset driver for SoCFPGA

Hi,

This patchset does the following for the SoCFPGA platform:

- Adds a DM reset manager driver
- Make the SoCFPGA platform use the DM I2C driver
- Adds i2c aliases and enable i2c for de0_nano_soc platform
- Adds a reset manager call to the i2c designware driver to look up
  any reset properties in the i2c dts node, and deassert the reset the
  IP if found.
- Adds CONFIG_DM_RESET to all the SoCFPGA defconfigs

For this patchset, I'm only enabling the i2c in the DTS for the Terasic
DE-0 Atlas board. I'll look to enable the other boards in the near future.
