Stefan Reinauer fb82ebe906 x86: Make sure boot device is mapped below 4G ...

On x86-64 the current way of calculating the base address
of the boot device (SPI flash) gets an unwanted sign extension,
making it live somewhere at the end of 64bit address space.

Enforce rom_base to be at the upper end of the 4G address space.
