Henrik Brix Andersen c894a6db4d drivers: counter: add counter_get_value(), deprecate counter_read()
Introduce a new counter API function for reading the current counter
value (counter_get_value()) and deprecate the former counter_read() in
favor of this.

Update all drivers and calling code to match the new counter API.

The previous counter driver API function for reading the current value
of the counter (counter_read()) did not support indicating whether the
read suceeded. This is fine for counters internal to the SoC where the
read always succeeds but insufficient for external counters (e.g. I2C
or SPI slaves).

Fixes #21846.

Anas Nashif 7e7a9bdf88 cleanup: include/: move counter.h to drivers/counter.h
move counter.h to drivers/counter.h and
create a shim for backward-compatibility.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Related to #16539

Piotr Zięcik 69406e0f9c counter: Update counter API in order to provide more flexibility
This commit introduces new top_value setting configuration structure
with flag for controlling resetting of the counter during change of
top value.

Such change allows for #12068 implementation on hardware which
does not provide alarms.

Krzysztof Chruscinski 89923134e7 drivers: counter: Add flags to counter_config_info structure
Allow further extention of counter API by replacing count_up bool in
the structure with u8_t flags where one bit is used for count up
feature.

Change is not breaking API as count up property is read using
counter_is_counting_up() that didn't change.

Patrik Flykt 97b3bd11a7 drivers: Rename reserved function names
Rename reserved function names in drivers/ subdirectory. Update
function macros concatenatenating function names with '##'. As
there is a conflict between the existing gpio_sch_manage_callback()
and _gpio_sch_manage_callback() names, leave the latter unmodified.
