The current device model enabled eeprom code only works if
CONFIG_SYS_I2C_EEPROM_BUS is set.
This patch makes it work without that define so that the bus
number passed to 'eeprom_init' is used.

- spi_init_f
- spi_init_r

- spi_write
these spi calls are exclusively for mpc8xx, but
the relevant driver is not available so remove it.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This converts the following to Kconfig:
CONFIG_SPI
This partly involves updating code that assumes that CONFIG_SPI implies
things that are specific to the MPC8xx SPI driver. For now, just update
the CONFIG tests. This also involves reworking the default for
CONFIG_SYS_DEF_EEPROM_ADDR so that we don't set it when we cannot make a
reasonable default, as it does not cause any compile failures.

Merge the parsing of layout aware and layout unaware eeprom commands into
one parsing function. With this change, layout aware commands now follow
the eeprom read and eeprom write conventions of making i2c bus and i2c address
parameters optional.

Introduce parse_i2c_bus_addr() to generalize the parsing of i2c bus number and
i2c device address. This is done in preparation for merging layout aware and
layout unaware command parsing into one function.

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.

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.

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.
