Merge tag '20200316-for-next' of https://gitlab.denx.de/u-boot/custodians/u-boot-i2c into next
i2c: for next
- i2c-gpio: make it possible to run deblock sequence on driver probe
- i2c-gpio: add clock stretching support
- updates the Designware I2C driver for high speed mode,
fix a bug and add some improvements.
- add DM support for memory based bootcounter driver
