edid: remove float use

First, we don't want floats in our code base.
Second, the calculation of the aspect ratio was wacky,
using a value guaranteed to be 0 for aspect ratio calculation.

While at it, define the aspect_* fields to be in tenths, to
provide some additional resolution. They were like that already
but we now also commit to that.
