mtd: rawnand: pl353: Set the nand chip node as the flash node

BugLink: https://bugs.launchpad.net/bugs/1969110
[ Upstream commit a1fe2ace2c39dcdc7c053705459a73b7598b1e4f ]

In devicetree the flash information is embedded within nand chip node,
so during nand chip initialization the nand chip node should be passed
to nand_set_flash_node() api, instead of nand controller node.
