Backport patches for support of generic spi-nor from SFDP data for kernel 6.1. Kernel 5.15 have major rework of the info flags and it's not trustable to backport this amount of changes and expect correct function of it. All affected patches automatically refreshed using make target/linux/refresh. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
