[PATCH v2 0/6] mtd: spi-nor: spring cleaning

It's time for some spring cleaning. Remove the oddball xilinx
flashes with non-power-of-2 page sizes.
Remove the .setup() callback, only the default callback is ever
used and it is unlikely there is need for a custom setup.

Finally, the last patch is a proposal how to deprecate flashes,
which are just detected by their id. We cannot really find out if
there are boards out there which are using a particular flash. Thus,
as a first step, we can print a warning during kernel startup. As a
second step we might introduce a kernel config option to actually
disable the flashes which has the deprecated flag.

v2:
- remove convert_addr, I've left page_size in the info, that might
still come in handy for future flashes as they are getting
bigger, although let's hope they have SFDP support..
- simplify the fast read flag handling
- reword the commit message of the .setup() callback removal patch
- introduce .deprecation_version and simplify the checking
