[PATCH 10/10 v2] Document I2C_MPC option for 86xx too.

[Jon Loeliger]

So, like, the other day Jean Delvare mumbled:
> Hi Jon,

Hi Jean,

There is a one-line commit message that will come from
the Subject: line.  If I add a paragraph, it will be

    "Document I2C_MPC option for 86xx too."

which will end up as a duplicate line in the commit message.

Thanks,
jdl
