iio: pressure: bmp280: Add missing bmp085 to SPI id table

"bmp085" is missing in bmp280_spi_id[] table, which leads to the next
warning in dmesg:

    SPI driver bmp280 has no spi_device_id for bosch,bmp085

Add "bmp085" to bmp280_spi_id[] by mimicking its existing description in
bmp280_of_spi_match[] table to fix the above warning.
