Michael Bacarella 8bed5efad7 Documentation/flash_tutorial/index.md: warn about dots painted on ICs
I fried my mainboard because I tried to orient my chip by lining a blue dot on
the corner of my chip with a dot depicted on the chip datasheet.  They
apparently have nothing to do with each other, and this is normal.  Add
warning about this to the docs to hopefully spare others from a similar fate.
