Patrick Rudolph 7a359497cd cpu/x86/64bit: Add code to call function in protected mode 
This adds a helper function for long mode to call some code in protected
mode and return back to long mode.

The primary use case is to run binaries that have been compiled for
protected mode, like the FSP or MRC binaries.

Tested on Intel Skylake. The FSP-M runs and returns without error while
coreboot runs in long mode.
