No need to zero the softc. It's allocated with M_ZERO.

Use pci_enable_busmaster instead of setting PCIM_CMD_BUSMASTEREN
directly. There's no need to set PCIM_CMD_MEMEN. The bit is set when a
SYS_RES_MEMORY resource is activated.

Remove redundant pci_* function calls from suspend/resume methods. The
bus driver already saves and restores the PCI configuration.

Write 1 byte instead of 4 when setting the HIFN_TRDY_TIMEOUT register.
It is only 1 byte according to the specification.

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.
