mtd: spi-nor: move the .id and .id_len into an own structure
...
Create a new structure to hold a flash ID and its length. The goal is to
have a new macro SNOR_ID() which can have a flexible id length. This way
we can get rid of all the individual INFOx() macros.

mtd: spi-nor: sysfs: print JEDEC ID for generic flash driver
...
We don't have a database entry for the generic SPI-NOR flash driver and
thus we don't have a JEDEC ID to print. Print the (cached) JEDEC ID
instead.

...
The manufacturer may be optional when pure SFDP flashes are supported.
Hide the sysfs property if no manufacturer is set.

...
Some non-jedec compliant flashes (like the Everspin flashes) don't have
an ID at all. Hide the attribute in this case.

mtd: spi-nor: add initial sysfs support
...
Add support to show the manufacturer, the partname and JEDEC identifier
as well as to dump the SFDP table. Not all flashes list their SFDP table
contents in their datasheet. So having that is useful. It might also be
helpful in bug reports from users.
