sf: Make flash->flags use for generic usage
Use the flash->flags for generic usage, not only for dm-spi-flash, this will be used for future flag additions. [Correct the spi flash flags detect logic] Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com> Signed-off-by: Jagan Teki <jteki@openedev.com>
