hwmon: (lm92) use permission-specific DEVICE_ATTR variants
Use DEVICE_ATTR_RO for read-only attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The conversion was done automatically using coccinelle. It was validated by compiling both the old and the new source code and comparing its text, data, and bss size.
