[PATCH 0/4] mtd: nand: Add special fixup kernel partitions for Denali

In the Denali NAND driver the partitions device node to fixup
for the kernel changed over time. This used to be a direct subnode
of the controller node, but Kernel v5.2 introduced an additional
subnode between the controller node and the partitions node.
Until then the binding complies with the current generic NAND
binding which has subnodes for each NAND chip under the controller
node.
We'll likely see that more often in the future. For now solve this
at driver level, but we might want to solve that in mtd code some
day.
