iio: adc: ad7476: Conditionally call convstart
The ad7476 supports two IC variants which may have a 'convstart' -GPIO
for starting the conversion. Currently the driver calls a function which
tries to access the GPIO for all of the IC variants, whether they
support 'convstart' or not. This is not an error because this function
returns early if GPIO information is not populated.
We can do a tad better by calling this function only for the ICs which
have the 'convstart' by providing a function pointer to the convstart
function from the chip_info structure, and calling this function only
for the ICs which have the function pointer set.
This does also allow to support ICs which require different convstart
handling than the currently supported ICs.
Call convstart function only on the ICs which can support it and allow
IC-specific convstart functions for the ICs which require different
handling.
