Boris Brezillon 2aaa5f7e0c mtd: spi-nor: Add a post BFPT parsing fixup hook
Experience has proven that SFDP tables are sometimes wrong, and parsing
of these broken tables can lead to erroneous flash config.

This leaves us 2 options:

1/ set the SPI_NOR_SKIP_SFDP flag and completely ignore SFDP parsing
2/ fix things at runtime

While #1 should always work, it might imply extra work if most of the
SFDP is correct. #2 has the benefit of keeping the generic SFDP parsing
logic almost untouched while allowing SPI NOR manufacturer drivers to
fix the broken bits.

Add a spi_nor_fixups struct where we'll put all our fixup hooks, each
of them being called at a different point in the scan process.

We start a hook called just after the BFPT parsing to allow fixing up
info extracted from the BFPT section. More hooks will be added if other
sections need to be fixed.
