FROMLIST: mtd: spi-nor: support dual, quad, and WP for Gigadevice
Gigadevice flash support BP{0,1,2,3,4} bits, where BP3 means the same as
the existing supported TB (Top/Bottom), and BP4 means the same as the
not-yet-supported 4K bit used on other flash (e.g., Winbond). Let's
support lock/unlock with the same feature flags as w25q32dw/w25q64dw.
Tested on gd25lq64c, but I checked datasheets for the other 3, to make
sure.
While I was at it, I noticed that these all support dual and quad as
well. I noted them, but can't test them at the moment, since my test
system only supports standard 1x SPI.
