From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

commit c9b9cfe7d342683f624a89c3b617be18aff879e8 upstream.

This driver uses IIO triggered buffers so it needs to select them in
Kconfig.

on riscv-32bit:

/opt/crosstool/gcc-13.2.0-nolibc/riscv32-linux/bin/riscv32-linux-ld: drivers/iio/imu/bno055/bno055.o: in function `.L367':
bno055.c:(.text+0x2c96): undefined reference to `devm_iio_triggered_buffer_setup_ext'
