ntb_perf: Add ntb_perf Makefile
Fix build errors for i386 and remove unecessary locks.
@mav: Apologies for the delay. I have not been able to get my hands on the ntb setup to test this thoroughly. However, I did fix the warnings and build errors. I will try once the setup is available.
Please try this on your setup and let me know if you face any issues.

Adding a fix for NMI latency.
Similar fix done in linux: https://lore.kernel.org/patchwork/patch/1062166/
PMCs interrupting at the same time are collapsed into one interrupt. With the current interrupt handler, the majority of samples are missing for one of the event when two such events are used (unhalted_cpu_cycles and retired_intructions). Out of the two, the one which is allocated first reports all the samples while the other one reports negligible numbers.

amd_intr() should only check core pmcs for interrupts since other types of pmcs (L3,DF) cannot generate interrupts.

@marius : Don't mean to badger, is there an alternate acceptable way I could go about increasing sdhci performance without increasing the DMA_BLOCK_SIZE. Or if you're planning to add ADMA support, can you maybe let us know when it might become available?

@marius : I know that you must be really busy with the upcoming release. Please review this if possible, I've made the necessary changes that you requested in the last review.

@marius : Are you working on adding ADMA support for sdhci(4) or planning to do so in the near future? If not, I might make an attempt to add ADMA2 support. I was not aware of the MAXPHYS limitation, increasing MAXPHYS to 1MB, I was able to get a further increase in throughput values. I got this idea from this thread (https://lists.freebsd.org/pipermail/freebsd-arch/2010-March/010022.html), where this seems to be a viable option for amd64 platforms.
