(Khali) Add section for lm75 in sensors.conf.eg
        Complete the lm78 section in sensors.conf.eg

No, I made this on purpose.

I wouldn't have changed an existing configuration, but it happens that
the LM75 had no section at that time, so I simply made one based on the
only board I had with a LM75 on it - an Asus TX97-E.

Now I admit that what's said on ticket 1423 is plain right. The LM75
cannot be configured in any way, so I hardly can understand how the
reported temperature could require scaling. On the other hand, which
chip would it be on my TX97-E, if not a LM75? There's also a LM78 on
that board, so it sound rather logical that the other monitoring chip
would be from National Semiconductor too.

I'll open the case and take a look, in case I'm able to see the
monitoring chips.
