Reduce duplicate definition in CAR code.
Macros for the register addresses for the MTRR MSRs are already defined
in include/cpu/x86/car.h. This patch uses those macros instead of
creating a second instance of that same data.
I also added a few macros to the amd mtrr.h to make the MSR naming more
consistent.
