Add support for some important configuration options and FSP memory init.
The memory init uses swizzle tables from the device tree.
Support for the FSP_S binary is also included.
Bootstage timing is used for both FSP_M and FSP_S and memory-mapped SPI
reads.

+ * and you have a native port.
+ *
+ * This function looks up a CBFS at a known location and reads the FSP-M from it
