This series remove the usage of the DM_I2C_COMPAT option for all the ti
platforms. It also takes this opportunity to not disable DM_I2C in the SPL.

There are a couples of issues to fix:
- CMD_EEPROM does not support the DM API. Fixed by removing this option
  when DM_I2C is used without DM_I2C_COMPAT
- i2c_get_chip_for_busnum() does not work when OF_CONTROL is not used
  (as is the case with am33xx SPL).
- The I2C driver do not support DM_I2C without OF_CONTROL.
- Most of the PMIC drivers do not support the I2C DM API.
- Board detection is done prior DM initialization. Fixed by moving it after
  DM is initialized. That move breaks the DRA7 platforms (The fixes for
  that are at the last 5 patches this series)

When all this is taken care of DM_I2C_COMPAT can be removed and DM_I2C
enabled in the SPL.

This has been tested with the following boards:
- am437x SK
- am335x SK
- am335x beaglebone (both DM and non-DM config)
- dra76 evm
- am572 evm
- k2g evm

The following targets may be impacted by the changes related to
SPL_OF_CONTROL and SPL_OF_PLATDATA:
- am3517_evm_defconfig
- omap3_logic_defconfig
- chromebit_mickey_defconfig
- chromebook_jerry_defconfig
- chromebook_minnie_defconfig
- evb-rk3399_defconfig
- rock_defconfig

It would be nice it some of you could try to boot them.


Changes in v3:
- removed commit introducing dm_i2c_probe_device(). Instead probe the
  presence of the chip on the I2C bus in i2c_get_chip_for_busnum().
- fdtdec_resetup() need not call fdtdec_setup() when only a single DTB is
  used.
- Add documentation in README-fdt-control explaining why and how to use
  fdtdec_resetup()

Changes in v2:
- Add missing commit log to the commit disabling CMD_EEPROM when non-DM API
  is not available
- don't use the DT to find the req_seq number if SPL_OF_PLATDATA is used.
  Instead do it as if SPL_OF_CONTROL is not defined.
- Also add DM_I2C support to the twl6030 driver
- remove the remaining non-DM I2C API call for pdu001 board.
- Fixed warning in power_init_board() for the am43xx ti boards.
