From: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>
Restore the status to be compatible with legacy devices. Take Freescale eSPI boot for example, it copies (in 3 Byte addressing mode) the RCW and bootloader images from SPI flash without firing a reset signal previously, so the reboot command will fail without reseting the addressing mode of SPI flash.
