[U-Boot] [PATCH 2/2] sf: Preserve QE bit when clearing BP# bits for Macronix flash

On some flash (like Macronix), QE (quad enable) bit is in the same status register as BP# bits, and we need preserve its original value during a reboot cycle as this is required by some platforms (like Intel ICH SPI controller working under descriptor mode). Signed-off-by: Bin Meng
