Initialize mtd->writesize in nand_init() as otherwise
nand_page_size() returns 0 and this affects NAND read
operations.

In nanddev_init mtd and memorg are assigned values that dereference nand
but this happens before a NULL check for nand. Move the assignments
after the NULL check.

The driver currently does:
    mtd->dev->parent = cadence->dev;

This works in Linux because `struct mtd_info` embeds a `struct device`,
so `mtd->dev` is always valid and its `.parent` can be set.

In U-Boot, however, `mtd->dev` is only a pointer to a `struct udevice`.
Dereferencing it before assignment is invalid, which breaks the device
hierarchy. As a result, consumers relying on `mtd->dev` (e.g. partition
parser, reset and re-init paths) operate on a dangling pointer. This
leads to failures during warm reset when the NAND device is accessed
again.

Fix by assigning the device pointer directly:
    mtd->dev = cadence->dev;

This matches U-Boot’s device model, preserves a valid hierarchy, and
resolves the warm reset issue on Cadence NAND.
