amd/model_fxx: set CPU_ADDR_BITS to 40 on all K8 machines
Moves the K8 CPU_ADDR_BITS definition from socket to model.
Previously socket_F was not setting CPU_ADDR_BITS correctly.
Tested on Sun Ultra 40 M2 with two 2nd-gen Opterons w/ 2x4x2GiB DIMMs.
Most if not all K8-based chips support 40-bit physical addresses, with
possible exception of IA32-only K8-based Athlon XP-M chips.
Probably irrelevant, unless your machine has enough memory (at least 60 to
64GiB before MMIO hoisting) to exceed the CPU_ADDR_BITS default of 36 from
src/cpu/x86/Kconfig.
