Please, separate the M29-specific quirks out to functions, do not inject
them to the main code.

Each quirk should be in a separate function, e.g.
'micron_m29_erase_quirk()'. The functions should have a descriptive
comment similar to what you added to the commit message. The function
just returns if the chip ID is not M29. This will be cleaner.
