security: Add common boot media write protection
Introduce boot media protection settings and use the existing
boot_device_wp_region() function to apply settings on all
platforms that supports it yet.
Also remove the Intel southbridge code, which is now obsolete.
Every platform locks the SPIBAR in a different stage.
For align up with the common mrc cache driver and lock after it has been
written to.
Tested on Supermicro X11SSH-TF. The whole address space is write-protected.
