mtd: spinand: gigadevice: add support for GD5FxGM7xExxG

Browse source

Add support for:
 GD5F{1,2}GM7{U,R}ExxG
 GD5F4GM8{U,R}ExxG

These are new 27nm counterparts for the GD5FxGQ4 chips from GigaDevice
with 8b/512b on-die ECC capability.
These chips (and currently supported GD5FxGQ5 chips) have QIO DTR
instruction for reading page cache. It isn't added in this patch because
I don't have a DTR spi controller for testing.
