platform/x86: dell-ddv: Fix temperature calculation

[ Upstream commit 7a248294a3145bc65eb0d8980a0a8edbb1b92db4 ]

On the Dell Inspiron 3505 the battery temperature is always
0.1 degrees larger than the temperature show inside the OEM
application.

Emulate this behaviour to avoid showing strange looking values
like 29.1 degrees.
