drivers/spi_flash: Always exit 4-byte address mode when memory-mapped
Always send the Exit 4-Byte Address Mode (E9h) command before the first
access to the SPI flash in all stages when the SPI flash is
memory-mapped. This is useful for x86 mainboards that do not access SPI
flash in bootblock yet still need to exit 4-byte addressing mode in
romstage or ramstage.
