flashchips: add GD25B512MF and GD25R512MF

GD25B512MF: 3V 512Mbit, QE = 1
GD25R512MF: GD25B512MF feature + RPMC
These two part share the same datasheet on the flash side.
https://www.gigadevice.com.cn/Public/Uploads/uploadfile/files/20240412/DS-00975-GD25B512MF-Rev1.1.pdf

Tested both models on ch347 with erase, write, read, and protection.
