Merge tag 'nand/for-5.6' into mtd/next

Raw NAND
* Macronix: Use match_string() helper
* Atmel: switch to using devm_fwnode_gpiod_get()
* Denali: rework the SKIP_BYTES feature and add reset controlling
* Brcmnand: set appropriate DMA mask
* Various cleanup.

Onenand drivers
* Rename Samsung and Omap2 drivers to avoid possible build warnings
* Enable compile testing
* Various build issues
* Kconfig cleanup

SPI-NAND
* Support for Toshiba TC58CVG2S0HRAIJ
