iio: adc: sun4i-gpadc-iio: Fix module autoload when PLATFORM devices are registered

If the driver is built as a module, it won't be autloaded if the devices
are registered via PLATFORM code because the PLATFORM device table
entries are not exported as aliases

Before the patch:
$ modinfo drivers/iio/adc/sun4i-gpadc-iio.ko | grep alias
$

After the patch:
$ modinfo drivers/iio/adc/sun4i-gpadc-iio.ko | grep alias
alias:          platform:sun6i-a31-gpadc-iio
alias:          platform:sun5i-a13-gpadc-iio
alias:          platform:sun4i-a10-gpadc-iio
