flashchips: add GD25B256E and GD25R256E
GD25B256E: 3V 256Mbit, Quad enabled.
GD25R256E: GD25B256E features + RPMC, so they share the same datasheet on flash side
https://www.gigadevice.com.cn/Public/Uploads/uploadfile/files/20230627/DS-00658-GD25B256E-Rev1.1.pdf
Tested both models on ch347 with erase, write, read and protection.
