dm: spi: Change cs_info op to return -EINVAL for invalid cs num
We need distinguish the following two situations in various SPI APIs:
- given chip select num is invalid
- given chip select num is valid, but no device is attached
Currently -ENODEV is returned for both cases.
For the first case, it's more reasonable to return -EINVAL instead of
-ENODEV for invalid chip select numbers.
