[PATCH] mtd: spi-nor: Add support for XM25Q series chips.

[Renjun Wang]

Add support for XM25QH32A, XM25QH64C, XM25QU64C, XM25QH128B, XM25QH128C,
XM25QU128C, XM25QH256C. These series chips are already tested on Orange
Pi boards[1].

I've just checked a few but they all had SFDP. Thus they don't need
an entry in the database as it is covered by the generic driver.

Also please read https://docs.kernel.org/driver-api/mtd/spi-nor.html

That's an ancient kernel.
