cfi_flash: Add optional config register write to cfi-detection
This patch adds the possibility to (optinally) write to the flash configuration register. The Intel style CFI chips support such a register that can be used to configure the operation mode to a non-default value. This method will be used by the t3corp board, which needs to configure the DS617 Xilinx flash for async read mode. Signed-off-by: Stefan Roese <sr@denx.de>
