ES0388 ('L452 errata) rev.5 - comment about MCO in "Spurious brown-out reset after short run sequence" erratum does not make sense without the accompanying figure

[waclawek.jan]

Given figure can be found in the respective erratum in ES0250 Rev 7 ('L476 errata).

And please remove the "modern feel and look" from this and all other errata.
