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.

Changes in v2:
- Merge separated patches into one
- Remove #ifdef CONFIG_SPI_FLASH_BAR

This look we have fixups for individual parts, better use default
fixup and handle it based on the part specific ID.
