spi-nand/spi-mem changes for 7.2

Hello Mark,

Here is an immutable tag for you to pull into your spi tree with all the spi-mem changes we agreed upon. I also merged it into nand/next.

Thanks,
Miquèl

spi: spi-mem: Add a no_cs_assertion capability (2026-05-04 15:07:37 +0200)

----------------------------------------------------------------
Aside from preparation changes in the SPI NAND core, the changes carried here focus on the shared spi-mem layer which is enhanced in order to bring two new features:

- The possibility to fill a primary and a secondary operation template in the direct mapping structure in order to support continuous reads in SPI NAND, which may require two different read operations.

- SPI controllers may indicate possible CS instabilities over long transfers by setting a boolean. This capability is related to the previous one, the need for it has arised while testing SPI NAND continuous reads with the Cadence QSPI controller which cannot, under certain conditions, keep the CS asserted for the length of an eraseblock-large transfer.
