iio: adc: ad7606: Add PWM support for conversion trigger
Until now, the conversion were triggered by setting high the GPIO
connected to the convst pin. This commit gives the possibility to
connect the convst pin to a PWM.
Connecting a PWM allows to have a better control on the samplerate,
but it must be handled with care, as it is completely decorrelated of
the driver's busy pin handling.
Hence it is not recommended to be used "as is" but must be exploited
in conjunction with IIO backend, and for now only a mock functionality
is enabled, i.e PWM never swings, but is used as a GPIO, i.e duty_cycle
== period equals high state, duty_cycle == 0 equals low state.
This mock functionality will be disabled after the IIO backend usecase
is introduced.
