This series enable I2C and EEPROM support on J721e common processor
board.

Logs: https://pastebin.ubuntu.com/p/HTrQk3VnZm/

Changes since v1:
- Fixed board_is_j721e_som() to use the right apis.

Use dm_i2c_probe() rather than i2c_get_chip() when trying to access
board-detection EEPROM devices. This has the advantage of more gracefully
handling the case when the EEPROM is not present by allowing to exit the
function early rather than failing and outputting an error message on the
I2C transactions that follow.

The TI J721E EVM system on module (SOM), the common processor board, and
the associated daughtercards have on-board I2C-based EEPROMs containing
board config data. Use the board detection infrastructure to do the
following:

1) Parse the J721E SOM EEPROM and populate items like board name, board
   HW and SW revision as well as board serial number into the TI common
   EEPROM data structure residing in SRAM scratch space
2) Check for presence of daughter card(s) by probing associated I2C
   addresses used for on-board EEPROMs containing daughter card-specific
   data. If such a card is found, parse the EEPROM data such as for
   additional Ethernet MAC addresses and populate those into U-Boot
   accordingly
3) Dynamically apply daughter card DTB overlays to the U-Boot (proper)
   DTB during SPL execution
4) Dynamically create an U-Boot ENV variable called name_overlays
   during U-Boot execution containing a list of daugherboard-specific
   DTB overlays based on daughercards found to be used during Kernel
   boot.

This patch adds support for the J721E system on module boards containing
the actual SoC ("J721EX-PM2-SOM", accessed via CONFIG_EEPROM_CHIP_ADDRESS),
the common processor board ("J7X-BASE-CPB"), the Quad-Port Ethernet
Expansion Board ("J7X-VSC8514-ETH"), the infotainment board
("J7X-INFOTAN-EXP") as well as for the gateway/Ethernet switch/industrial
expansion board ("J7X-GESI-EXP").
