x86: fsp: Support a warning message when DRAM init is slow
With DDR4, Intel SOCs take quite a long time to init their memory. During
this time, if the user is watching, it looks like SPL has hung. Add a
message in this case.
This works by adding a return code to fspm_update_config() that indicates
whether MRC data was found and a new property to the device tree.
Also add one more debug message while starting.
