6810ad6f2a Overhaul driver/subsystem api's:
o make all crypto drivers have a device_t; pseudo drivers like the s/w
  crypto driver synthesize one
o change the api between the crypto subsystem and drivers to use kobj;
  cryptodev_if.m defines this api
o use the fact that all crypto drivers now have a device_t to add support
  for specifying which of several potential devices to use when doing
  crypto operations
o add new ioctls that allow user apps to select a specific crypto device
  to use (previous ioctls maintained for compatibility)
o overhaul crypto subsystem code to eliminate lots of cruft and hide
  implementation details from drivers
o bring in numerous fixes from Michale Richardson/hifn; mostly for
  795x parts
o add an optional mechanism for mmap'ing the hifn 795x public key h/w
  to user space for use by openssl (not enabled by default)
o update crypto test tools to use new ioctl's and add cmd line options
  to specify a device to use for tests

These changes will also enable much future work on improving the core
crypto subsystem; including proper load balancing and interposing code
between the core and drivers to dispatch small operations to the s/w
driver as appropriate.

These changes were instigated by the work of Michael Richardson.

aa959e0d17 Update support for 795x parts:
o rework pll setup code to follow h/w specification
o add hint.hifn.X.pllconfig to specify reference clock setup
  requirements; default is pci66 which means the clock is
  derived from the PCI bus clock and the card resides in a
  66MHz slot

Tested on 7955 and 7956 cards; support for 7954 cards not enabled
since we have no cards to test against.

In collaboration with Poul-Henning Kamp.

fe9b390b9d Move session state from on-card memory to host memory so we no longer are
constrained to a small number of sessions by the small on-card memories found
in newer devices.  This is really a stopgap solution as having session state
in main memory incurs a (small but noticeable) performance penalty. The better
solution is to manage session state so that it's cached on chip.

17b667019e Add symmetric crypto support for the 7955 and 7956.
Note performance is currently suboptimal.

b7c4858f1e o add crypto driver glue for using the new rndtest driver/module; this is
conditional in each driver on foo_RNDTEST being defined_
o bring HIFN_DEBUG and UBSEC_DEBUG out to be visible options; they control
  the debugging printfs that are set with hw.foo.debug (e.g. hw.hifn.debug)
