[U-Boot] [PATCH v2 0/2] dm: i2c: implement gpio-based I2C deblock

[Alexander Kochetkov]

Hello, Heiko!     

Here is try2 of my previous patch[1].

Done in v2:
- fix checkpatch warnings
- ENOSYS warning still present, but it was in original code also 
  and for me it looks like -ENOSYS must be returned in case of
  missed i2c_deblock_gpio() implementation.
    WARNING: ENOSYS means 'invalid syscall nr' and nothing else
    #138: FILE: drivers/i2c/i2c-uclass.c:552:
    +   return -ENOSYS;
- fix travis build, results can be viewed here:
  https://travis-ci.org/akochetkov/u-boot/builds/358822512
- add property description to i2c.txt

I have question. I declared PIN_SDA, PIN_SCL, PIN_COUNT constants for
i2c-uclass.c. The same constants exist in the i2c-gpio.c. Should I place    
them into i2c.h or may leave as is?
