Subject: [PATCH 5.5 062/119] iio: chemical: sps30: fix missing triggered buffer dependency

From: Petr Štetiar <ynezz@...e.cz>

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.
