iio: light: rpr0521: add missing Kconfig dependencies

Browse Source 
[ 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.
