Done to resolve conflicts with header reorg around mod_devicetable.h
and provide a base for other inflight series that touch the includes.
Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.
The mentioned robustness is relevant for a planned change to struct
spi_device_id that replaces .driver_data by an anonymous union.
This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

- High-resolution frequency calculations using microhertz (µHz) precision
to handle sub-Hz resolution across multi-GHz frequency ranges;
- IIO debugfs interface for direct register access;
- FW property parsing from devicetree including charge pump settings and
reference path configuration;

Replace manual mutex_lock()/mutex_unlock() calls with guard(mutex)() from
cleanup.h.
Using guard(mutex)() from cleanup.h allows the compiler to enforce lock
release on every exit path, eliminating the error-prone manual lock/unlock
pattern and the goto-based exit labels that existed in adf4377_get_freq()
and adf4377_set_freq(). This reduces the chance of lock imbalance bugs.

The ADRF6780 datasheet (Rev. D, page 23, ADC section) says:
"Wait approximately 200 us for the ADC to be ready."
fsleep(200) expands to the same usleep_range(200, 250). Use the
flexible sleep helper, which picks the right primitive for the
given microsecond delay.

The regmap_read_poll_timeout() uses ADF4377_0000_SOFT_RESET_R_MSK
twice instead of checking both SOFT_RESET_MSK (bit 0) and
SOFT_RESET_R_MSK (bit 7). This causes an incomplete reset status check.
The code first sets both SOFT_RESET and SOFT_RESET_R bits to 1 via
regmap_update_bits(), then polls for them to be cleared. Since we set
both bits before polling, we should be waiting for both to clear.
Fix by using both masks as done in regmap_update_bits() above.

The ADF4350/1 features a programmable dual-modulus prescaler of 4/5 or 8/9.
When set to 4/5, the maximum RF frequency allowed is 3 GHz.
Therefore, when operating the ADF4351 above 3 GHz, this must be set to 8/9.
In this context not the RF output frequency is meant
- it's the VCO frequency.
Therefore move the prescaler selection after we derived the VCO frequency
from the desired RF output frequency.
This BUG may have caused PLL lock instabilities when operating the VCO at
the very high range close to 4.4 GHz.

When `devm_add_action_or_reset()` fails, it is due to a failed memory
allocation and will thus return `-ENOMEM`. `dev_err_probe()` doesn't do
anything when error is `-ENOMEM`. Therefore, remove the useless call to
`dev_err_probe()` when `devm_add_action_or_reset()` fails, and just
return the value instead.

The variable ret is being assigned a return value and non-zero error
return paths are taken at all stages. At the end of the function ret
is always zero, so the ternary operator checking for zero ret is
redundant and can be replaced with just len instead.

Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace
the array sentinel in all IIO drivers to the same style.
For some time, we've been trying to consistently use `{ }` (no trailing
comma, no comment, one space between braces) for array sentinels in the
IIO subsystem. Still nearly 50% of existing code uses a different style.
To save reviewers from having to request this trivial change as
frequently, let's normalize the style in all existing IIO drivers.
At least when code is copy/pasted to new drivers, the style will be
consistent.

To use spi_get_device_match_data(), add the chip_info structure to the
