[RFC] iio: accel: st_accel: silent spi_device_id warnings

  Add and correct spi_device_id entries to silent following warnings:
 SPI driver st-accel-spi has no spi_device_id for st,lis302dl-spi
 SPI driver st-accel-spi has no spi_device_id for st,lis3lv02dl-accel
 SPI driver st-accel-spi has no spi_device_id for st,lis3dh-accel
 SPI driver st-accel-spi has no spi_device_id for st,lsm330d-accel
 SPI driver st-accel-spi has no spi_device_id for st,lsm330dl-accel
 SPI driver st-accel-spi has no spi_device_id for st,lsm330dlc-accel
 SPI driver st-accel-spi has no spi_device_id for st,lis331dlh-accel
 SPI driver st-accel-spi has no spi_device_id for st,lsm330-accel
 SPI driver st-accel-spi has no spi_device_id for st,lsm303agr-accel
 SPI driver st-accel-spi has no spi_device_id for st,lis2dh12-accel
 SPI driver st-accel-spi has no spi_device_id for st,lng2dm-accel
 SPI driver st-accel-spi has no spi_device_id for st,h3lis331dl-accel
 SPI driver st-accel-spi has no spi_device_id for st,lis331dl-accel
 SPI driver st-accel-spi has no spi_device_id for st,lsm303c-accel

Is the names with underscore from ACPI or?
Is it fine to do this?

Ancient history for the _ and I suspect no particularly strong reason for it.

Hmm. I 'think' the only breakage would be to user space scripts that might
rely on poking the device add stuff for i2c which is affected by this even
though the warning is about SPI.  Also to any userspace that was matching
on the iio name which this fills (I think)

If that's a potential problem we will need to keep underscores for that
purpose whilst using - for the ID tables which is messy.

Bit odd that this driver replaces spi->modalias like it does. Should probably
operate on a separate string

It may be a case of fingers crossed - however, +CC Dennis in case
he can remember and his email address still works...
