iio: trigger: stm32-lptimer-trigger: remove unneeded platform_set_drvdata()
...
This function call was found to be unnecessary as there is no equivalent
platform_get_drvdata() call to access the private data of the driver. Also,
the private data is defined in this driver, so there is no risk of it being
accessed outside of this driver file.

iio: trigger: stm32-lptimer-trigger: explicitly add proper header files
...
Do not trust the fact that iio.h includes of.h which in turn includes
all the headers we are relying on.
The ultimate goal is to actually drop of.h from iio.h.

The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure

iio: trigger: Add STM32 LPTimer trigger driver
...
Add support for LPTIMx_OUT triggers that can be found on some STM32
devices. These triggers can be used then by ADC or DAC.
Typical usage is to configure LPTimer as PWM output (via pwm-stm32-lp)
and have synchronised analog conversions with these triggers.
