Update SVR numbers to expand support
FSL has taken to using SVR[16:23] as an SOC sub-version field. This is used to distinguish certain variants within an SOC family. To account for this, we add the SVR_SOC_VER() macro, and update the SVR_* constants to reflect the larger value. We also add SVR numbers for all of the current variants. Finally, to make things neater, rather than use an enormous switch statement to print out the CPU type, we create and array of SVR/name pairs (using a macro), and print out the CPU name that matches the SVR SOC version.
