In Zephyr v2.7, DT_ENUM_TOKEN is deprecated in favor of
DT_STRING_TOKEN. Additionally, DT_ENUM_UPPER_TOKEN is deprecated in
favor of DT_STRING_UPPER_TOKEN.
See the v2.7 release notes for details:
https://docs.zephyrproject.org/latest/releases/release-notes-2.7.html
Since we backported the DT_STRING_* macros to our v2.6 branch, let's
switch to them ahead of time to prepare for the v2.7 uprev.
Note: the DT_STRING_* macros are compatible with Zephyr's device tree
enums, but also allow non-enum properties to be used in the same
fashion. This commit does the bare minimum for compatibility with
v2.7, i.e., just swap the macros without dropping enum properties
anywhere. We should investigate whether we want to continue using the
enum properties or abandon some of them for any string in the future.

ZephyrEC uses different I2C port numbers than CrosEC does, so convert
the received remote port via I2C_PASSTHRU command into a proper one.
The conversion is done based on a new property remote-port, which tells
what port number is used by external components like kernel.
The change fixes an issue with unexpected entering OTG mode by the
charger.

The SDA and SCL components of the struct i2c_port_t are only used in
and for the i2c_wedge.c logic. This isn't needed in Zephyr. Remove
the values and functions that use them from the Zephyr build.

This makes a separate dts node for the CBI EEPROM. The node uses the
existing at24 dts binding and defines all the required properties, even
though right now only the address is used.

Currently, every project will need to provide a custom mapping header
for i2c as well as gpios. We'd like to move that overhead to the dts
files, which will make the board dts a lot more reusable as well as
clean up the bringup of new boards.
Add to the i2c_ports enum from the dts named i2c port list. Each enum
is only added if a node exists using that enum. This also allowes for
verifying that the enum is only used once.

We have quite a few options already and plan to add more. Sort them to
make it easier to see what is there.
The I2C enum isn't really connected with the basic CONFIG munging done
in config_chip.h so move it to i2c.h instead.
Fix the 'keybaord' typo while we are here.

This change accomplishes 2 things:
1. It refactors the zephyr/shim directory to structure around
chip specific compilation. In this example, we're focusing
on npcx7m6fb which is used in volteer but others can be
added easily.
2. It shims the common/i2c_master.c by providing an alternate
implementation of i2c_xfer_unlocked that calls down to the
Zephyr API i2c_write_read instead of the chip specific
i2c_xfer_no_retry or chip_i2c_xfer_with_notify.
The shim layer is made possible by the addition of
zephyr/shim/include/i2c/i2c.h which adds a functions that
needs to be implemented per chip (npcx7 family in this case)
and allows us to map the current port int which is defined
in chip/${CHIP}/registers.h (chip/npcx/registers-npcx7.h in
our case). This function (i2c_get_device_for_port) maps the
platform/ec port int to a const struct device * which is
needed in the Zephyr I2C APIs.
