Raw NAND

The main series brought is an update of the Broadcom support to support
all BCMBCA SoCs and their specificity (ECC, write protection,
configuration straps), plus a few misc fixes and changes in the main
driver. Device tree updates are also part of this PR, initially because
of a misunderstanding on my side.

The STM32_FMC2 controller driver is also upgraded to properly support
MP1 and MP25 SoCs.

A new compatible is added for an Atmel flavor.

Among all these feature changes, there is as well a load of continuous
read related fixes, avoiding more corner conditions and clarifying the
logic. Finally a few miscellaneous fixes are made to the core, the
lpx32xx_mlc, fsl_lbc, Meson and Atmel controller driver, as well as
final one in the Hynix vendor driver.

SPI-NAND

The ESMT support has been extended to match 5 bytes ID to avoid
collisions. Winbond support on its side receives support for W25N04KV
chips.
