aa9e604410 cmd: eeprom: add support for layout aware commands
Introduce the (optional) eeprom print and eeprom update commands.

These commands are eeprom layout aware:
* The eeprom print command prints the contents of the eeprom in a human
  readable way (eeprom layout fields, and data formatted to be fit for human
  consumption).
* The eeprom update command allows user to update eeprom fields by specifying
  the field name, and providing the new data in a human readable format (same
  format as displayed by the eeprom print command).
* Both commands can either auto detect the layout, or be told which layout to
  use.

New CONFIG options:
CONFIG_CMD_EEPROM_LAYOUT - enables commands.
CONFIG_EEPROM_LAYOUT_HELP_STRING - tells user what layout names are supported

Feature API:
__weak int parse_layout_version(char *str)
	- override to provide your own layout name parsing
__weak void __eeprom_layout_assign(struct eeprom_layout *layout, int layout_version);
	- override to setup the layout metadata based on the version
__weak int eeprom_layout_detect(unsigned char *data)
	- override to provide your own algorithm for detecting layout version
eeprom_field.c
	- contains various printing and updating functions for common types of
	  eeprom fields. Can be used for defining custom layouts.

2636ac65a8 cmd: eeprom: add bus switching support for all i2c drivers
The i2c_init function is always provided when CONFIG_SYS_I2C is
defined. No need to limit ourselves to just one supported I2C driver
(soft_i2c). Update the #ifdef conditions to support bus switching for
all I2C drivers.

a6e7b7744e i2c/eeprom: Always define I2C_RXTX_LEN
I2C_RXTX_LEN from include/i2c.h is not defined if CONFIG_DM_I2C is
enabled. This leads to a compilation error on boards that enable both
CONFIG_CMD_EEPROM and CONFIG_DM_I2C.

To avoid this, we define I2C_RXTX_LEN in cmd/eeprom.c if it is not
already defined.

2e192b245e Remove the cmd_ prefix from command files
Now that they are in their own directory, we can remove this prefix.
This makes it easier to find a file since the prefix does not get in the
way.
