[PATCH 5.4 056/102] iio: chemical: sps30: fix missing triggered buffer dependency

[Greg Kroah-Hartman]

From: Petr Åtetiar <ynezz@xxxxxxx>

commit 016a8845f6da65b2203f102f192046fbb624e250 upstream.

SPS30 uses triggered buffer, but the dependency is not specified in the
Kconfig file.  Fix this by selecting IIO_BUFFER and IIO_TRIGGERED_BUFFER
config symbols.
