mtd: spi-nor: Add support for Spansion S25FL256L
The S25FL256L is a part of the S25FL-L family and has the same feature set as S25FL128L except the density. The datasheet can be found in the following link. https://www.cypress.com/file/316171/download The S25FL256L is 32MB NOR Flash that does not support Bank Address Register. This fixup is activated if CONFIG_SPI_FLASH_BAR is enabled and returns ENOTSUPP in setup() hook to avoid further ops. Tested on Xilinx Zynq-7000 FPGA board.
