[PATCH v2] iio: accel: kxsd9: declare missing of table

[Daniel Gomez]

Add missing <of_device_id> table for SPI driver relying on SPI
device match since compatible is in a DT binding or in a DTS.

Before this patch:
modinfo drivers/iio/accel/kxsd9-spi.ko  | grep alias
alias:          spi:kxsd9

After this patch:
modinfo drivers/iio/accel/kxsd9-spi.ko  | grep alias
alias:          spi:kxsd9
alias:          of:N*T*Ckionix,kxsd9C*
alias:          of:N*T*Ckionix,kxsd9
