Documentation: Use correct KiB/MiB units instead of KB/MB

Browse Source 
Fix a common mistake of using KB/MB where KiB/MiB is what actually is meant.

1 MB = (10^3)^2 = 1000000
1 MiB = (2^10)^2 = 1048576

The ifdtool can be used to manipulate a firmware image with a IFD. This tool
will not take into account the FMAP while modifying the image which can lead to
unexpected and hard to debug issues with the firmware image. For example if the
ME region is defined at 6 MB in the IFD but the FMAP only allocates 4 MB for the
ME, then when the ME is added by the ifdtool 6 MB will be written which could
overwrite 2 MB of the BIOS.

In order to validate that the FMAP and the IFD are compatible the ifdtool
provides --validate (-t) option. `ifdtool -t` will read both the IFD and the
