[PATCH] staging:iio:adis16260: select IIO_ADIS_LIB to fix build error

[Yuanhan Liu]

Commit 9d5e9fdf turned the code to use adis library, so it depends on
adis lib. But it forgot to select it at Kconfig file. Thus if adis is
not enabled, it will produce following build errros(catched by Fengguang's
0-DAY kernel build testing system):
  ERROR: "adis_initial_startup" [drivers/staging/iio/gyro/adis16260.ko] undefined!
  ERROR: "adis_init" [drivers/staging/iio/gyro/adis16260.ko] undefined!
  ERROR: "adis_write_reg" [drivers/staging/iio/gyro/adis16260.ko] undefined!
  ERROR: "adis_read_reg" [drivers/staging/iio/gyro/adis16260.ko] undefined!
  ERROR: "adis_single_conversion" [drivers/staging/iio/gyro/adis16260.ko] undefined!

Selecting IIO_ADIS_LIB at Kconfig file fixes this issue.
