[PATCH] mtd: spi-nor: Update XM25QH512C to XM25QH512D

[Ssunk]

The XM25QH512C has been replaced by XM25QH512D. Both share the same
JEDEC ID (0x204020) and have identical parameters. Update the flash
name to reflect the current part in use.

Please provide a Signed-off-by here along with datasheet or the product
page referencing the change to the product's name. As I see now, both
the parts are listed on XMCWH's website[1] with unique names.
