ccp: Don't name anonymous structure and union types
Keep the dword labels as comments instead. Anonymous structs and
unions don't have type names in C11+.

Remove residual blank line at start of Makefile
This is a residual of the $FreeBSD$ removal.
MFC After: 3 days (though I'll just run the command on the branches)

Add ccp(4): experimental driver for AMD Crypto Co-Processor
* Registers TRNG source for random(4)
* Finds available queues, LSBs; allocates static objects
* Allocates a shared MSI-X for all queues.
Add ccp(4): experimental driver for AMD Crypto Co-Processor
* Registers TRNG source for random(4)
* Finds available queues, LSBs; allocates static objects
* Allocates a shared MSI-X for all queues. The hardware does not have
separate interrupts per queue. Working interrupt mode driver.
* Computes SHA hashes, HMAC. Passes cryptotest.py, cryptocheck tests.
* Does AES-CBC, CTR mode, and XTS. cryptotest.py and cryptocheck pass.
* Support for "authenc" (AES + HMAC). (SHA1 seems to result in
"unaligned" cleartext inputs from cryptocheck -- which the engine
cannot handle. SHA2 seems to work fine.)
* GCM passes for block-multiple AAD, input lengths
Largely based on ccr(4), part of cxgbe(4).
Rough performance averages on AMD Ryzen 1950X (4kB buffer):
aesni: SHA1: ~8300 Mb/s SHA256: ~8000 Mb/s
ccp: ~630 Mb/s SHA256: ~660 Mb/s SHA512: ~700 Mb/s
cryptosoft: ~1800 Mb/s SHA256: ~1800 Mb/s SHA512: ~2700 Mb/s
As you can see, performance is poor in comparison to aesni(4) and even
cryptosoft (due to high setup cost). At a larger buffer size (128kB),
throughput is a little better (but still worse than aesni(4)):
aesni: SHA1:~10400 Mb/s SHA256: ~9950 Mb/s
ccp: ~2200 Mb/s SHA256: ~2600 Mb/s SHA512: ~3800 Mb/s
cryptosoft: ~1750 Mb/s SHA256: ~1800 Mb/s SHA512: ~2700 Mb/s
AES performance has a similar story:
aesni: 4kB: ~11250 Mb/s 128kB: ~11250 Mb/s
ccp: ~350 Mb/s 128kB: ~4600 Mb/s
cryptosoft: ~1750 Mb/s 128kB: ~1700 Mb/s
This driver is EXPERIMENTAL. You should verify cryptographic results on
typical and corner case inputs from your application against a known- good
implementation.
