Move the two functions in fixme.c to places where they make more sense.
Coincidentally fix the todo in amd_initcpuio() and use bsp_topmem()
instead of explicitely reading the MSR.

Change the Stoney Ridge SOC to a more modern method for setting up
the multiple cores.
Add a new cpu.c file for most of the processor initiliazation. Build
mp_ops with the necessary callbacks. Note also that this patch removes
cpu_bus_scan. Rather than manually find CPUs and add them to the
devicetree, allow this to be done automatically in the generic
mp_init.c file.
SMM information is left blank in mp_ops to avoid having mp_init.c
install a handler at this time. A later patch will add TSEG SMM
capabilities for the APU.
This patch also contains a hack to mask the behavior of AGESA which
configures the MTRRs and Tom2ForceMemTypeWB coming out of AmdInitPost.
The hack immediately changes all WB variable MTRRs, on the BSP, to UC
so that all writes to memory space will make it to the DRAM.

Remove the check for the southbridge link from Stoney Ridge. The APU
is an SoC which can never be installed in a multi-node system. It is
pointless to detect and remember the sblink value, which is set by
hardware and comes up 0. The BKDG marks this as a reserved field vs.
documentation for multi-node-capable Family 15h devices.
Because there is only one option for SB link now, relocate the register
write done by set_vga_enable_reg() and remove the function.

Also make other misc. changes, e.g. consistency in lower-case

These changes were confirmed to cause no changes in a Gardenia
