flashchips: add GD25B256E and GD25R256E

removed FEATURE_WRSR_EXT2 from the model after datasheet review.
replace
printlock	= SPI_PRETTYPRINT_STATUS_REGISTER_BP3_SRWD,
.unlock		= SPI_DISABLE_BLOCKPROTECT,

with

.printlock	= SPI_PRETTYPRINT_STATUS_REGISTER_BP4_SRWD,
.unlock		= SPI_DISABLE_BLOCKPROTECT_BP4_SRWD,

GD25B256E: 3V 256Mbit, Quad enabled.
GD25R256E: GD25B256E features + RPMC, so they share the same datasheet on flash side

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