8f1e881a2f hwmon: f75308: Fix build for Linux v6.11 
The macro of_property_for_each_u32() was updated for Linux v6.11 to
remove two of the arguments that were only used internally in the macro
and do not need to be passed. Add a test to conftest to detect the
version of the of_property_for_each_u32() that is present in the kernel
and fix the f75308 driver accordingly.

3c38a2fe6f pwm: tachometer: Fix build for Linux v6.1 
Upstream Linux kernel commit b88c48bfdd85 ("pwm: core: Get rid of unused
devm_of_pwm_get()") has removed the function devm_of_pwm_get() which
breaks building the Tegra PWM tachometer driver with Linux v6.1-rc1.
Fix this by updating the driver to use the function
devm_fwnode_pwm_get() instead.
