Subject: [PATCH v2 0/2] Enable WC+ memory type on AMD family 10h processors

Resending since previous message went with incorrect From header. Also
fixing redundant check in the second patch.

Enable WC+ memory type on AMD family 10h processors if BIOS doesn't do
this. WC+ is used only in in virtualized scenarios and never in bare metal
cases (see AMD APM v2).

Also clean up init_amd() a little.
