arch/cpu/x86: Update AMD detection 

AMD Picasso, and later, will not use CPU_AMD_AGESA or CPU_AMD_PI.
Those two symbols indicate an Arch2008 system.  Add SOC_AMD_COMMON
to cause cpu_is_amd() to return TRUE on Picasso.

This removes an error message of "Unknown CPU".

The patch also assumes AMD Family 10h and non-AGESA Family 15h
devices were seeing the "Unknown CPU" message.  No functionality
has been verified on these devices.
