Subject: [PATCH] mtd: spi-nor: gigadevice: add support for gd25lq128e

The GD25LQ128EWIGR[0] reports an JEDEC id with a different vendor,
otherwise it seems to fit neatly in the gigadevice list.

Tested to work on the Pine64 PinePhone Pro[1].

Attribution: initial version was written by
Martijn Braam <martijn@...xit.nl> for the Pine64 vendor kernel[2].

Also in use in vendor u-boot builds[3].
