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

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

Before 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

After the patch:
$ modinfo drivers/iio/adc/sun4i-gpadc-iio.ko | grep alias
alias:          of:N*T*Callwinner,sun8i-a33-thsC*
alias:          of:N*T*Callwinner,sun8i-a33-ths
alias:          platform:sun6i-a31-gpadc-iio
alias:          platform:sun5i-a13-gpadc-iio
alias:          platform:sun4i-a10-gpadc-iio
