hwmon: (lm90) use permission-specific DEVICE_ATTR variants

Browse Source 
Use DEVICE_ATTR_RW for read/write 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.
