Consistently place C++ use of extern "C" after all include directives,
within the negative branch of _ASMLANGUAGE if used.
Only updated in headers that already had support for drivers built with
a C++ compiler.
The spi_dw.h file defines macros to declare functions, then uses them
within a file that may have out-of-tree overrides. In this case we
leave the including file extern "C" active for backward compatibility.
Background from issue #17997:
Declarations that use C linkage should be placed within extern "C"
so the language linkage is correct when the header is included by
a C++ compiler.
Similarly #include directives should be outside the extern "C" to
ensure the language-specific default linkage is applied to any
declarations provided by the included header.

We generated a define for each instance to convey its existance of the
form:
#define DT_<COMPAT>_<INSTANCE> 1
However we renamed all other instance defines to be of the form
DT_INST_<INSTANCE>_<FOO>. To make things consistent we now generate a
define of the form:
#define DT_INST_<INSTANCE>_<COMPAT> 1
We also now deprecate the DT_<COMPAT>_<INSTANCE> form and fixup all uses
to use the new form.

Make use of the new flag introduced in nrfx v1.7.2 that suspends
transfers, in order to properly handle scattered I2C transactions,
especially to perform i2c_burst_write() in the way expected by
display drivers, i.e. as a continuous transaction on the bus,
without the repeated START between its two parts.

The i2c_cc32xx driver used system clock frequency
as a base for I2C clock frequency calculation.
This commit corrects that by obtaining the needed value from DTS.
Please note, that for I2C devices the clock-frequency property
specifies SCK frequency, instead of frequency of the clock driving
peripheral. To solve that problem, a new property was added.

On some SoCs the frequency of the system clock is obtained at run time
as the exact configuration of the hardware is not known at compile time.
On such platforms using CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC define
directly introduces timing errors.
This commit replaces CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC by the call to
inline function sys_clock_hw_cycles_per_sec() which always returns
correct frequency of the system clock.

The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.
To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.
This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.
