This uses newly added Patina monitor commands to get the MTRR value on x86 for a PA and the MAIR on ARM64 to parse the CacheIndex. This is a backwards compatible change, if the monitor command/output is not available, "Unknown" will be printed instead of the cache type. In addition, this updates the ARM64 !pt command to read TTBR0_EL2 automatically instead of requiring it to be passed in. Signed-off-by: Oliver Smith-Denny <osde@microsoft.com>
