[ Upstream commit 6ac12303572ef9ace5603c2c07f5f1b00a33f580 ]
Fix an implicit declaration of function error for rpr0521 under some configs
When CONFIG_RPR0521 is enabled without CONFIG_IIO_TRIGGERED_BUFFER, the build results in "implicit declaration of function" errors, e.g., drivers/iio/light/rpr0521.c:434:3: error: implicit declaration of function 'iio_trigger_poll_chained' [-Werror=implicit-function-declaration] 434 | iio_trigger_poll_chained(data->drdy_trigger0); | ^~~~~~~~~~~~~~~~~~~~~~~~
This fix adds select dependencies to RPR0521's configuration declaration.
