Two members of the same or quite similar semantics is quite confusing
to begin with. Moreover, fwnode covers all possible firmware descriptions
that Linux kernel supports. Deprecate of_node in struct i2c_board_info,
so users will be warned and in the future there is a plan to convert
the users and remove it completely.

i2c-host updates for v6.15

Refactoring and cleanups
 - octeon, cadence, i801, pasemi, mlxbf, bcm-iproc: general
   refactorings
 - octeon: remove 10-bit address support

Improvements
 - amd-asf: improved error handling
 - designware: use guard(mutex)
 - amd-asf, designware: update naming to follow latest specs
 - cadence: fix cleanup path in probe
 - i801: use MMIO and I/O mapping helpers to access registers
 - pxa: handle error after clk_prepare_enable

New features
 - added i2c_10bit_addr_*_from_msg() and updated multiple drivers
 - omap: added multiplexer state handling
 - qcom-geni: update frequency configuration
 - qup: introduce DMA usage policy

New hardware support
 - exynos: add support for Samsung exynos7870
 - k1: add support for spacemit k1 (new driver)
 - imx: add support for i.mx94 lpi2c
 - rk3x: add support for rk3562

Multiplexers
 - ltc4306, reg: fix assignment in platform_driver structure

There are already a lot of drivers that have been using
i2c_8bit_addr_from_msg() for 7-bit addresses, now it's time
to have the similar for 10-bit addresses.

When adding the new debugfs entry, its kdoc equivalent was forgotten.
Add it now.

More and more I2C client drivers use debugfs entries and currently they
need to manage a subdir for their files on their own. This means
inconsistent naming for these subdirs and they are scattered all over
the debugfs-tree as well. Not to mention the duplicated code.

Let the I2C core provide and maintain a proper directory per client.

Note: It was considered to save the additional pointer in 'struct
i2c_client' and only provide a subdir when requested via a helper
function. When sketching this approach, more and more corner cases
appeared, though, so the current solution with its simple and unabiguous
code was chosen.

Similar to the list of auto-detected clients, we can also replace the
list of userspace-created clients with flagging such client devices.
