The sci_object.h file was removed. No sci_base_object
is now in the code.

Merge struct sci_base_controller into scic_sds_controller, and also factor
the two types of state machine handlers into one function. While we're at
it also remove lots of duplicate incorrect kerneldoc comments for the state
machine handlers.

We need to scan the OROM for signature and grab the OEM parameters. We
also need to do the same for EFI. If all fails then we resort to user
binary blob, and if that fails then we go to the defaults.
Share the format with the create_fw utility so that all possible sources
of the parameters are in-sync.

Until we synchronize against device removal this limits the damage of
use after free bugs to the driver's own objects. Unless we implement
reference counting we need to ensure at least a subset of a remote
device is valid at all times. We follow the lead of other libsas
drivers that also preallocate devices.
This also enforces maximum remote device accounting at the lldd layer,
but the core may still run out of RNC's before we hit this limit.

Removed all callbacks in the deprecated.c. Core will call the appropriate

We can copy the data directly to and from sg for SATA PIO read operations.
There is no reason to involve the hardware SGL. In the process we also need
to kmap the sg because we don't know where that can come from.
We also do to not call phys_to_virt(). The driver already has the information.
We can just calculcate the appropriate offets.

Moved the firmware loading from per adapter to per PCI device. This should
prevent firmware from being loaded twice becuase of 2 SCU controller per
PCI device. We do have to do it per PCI device because request_firmware()
requires a struct device passed in.

The indirection is unecessary and broken in the current case that assigns the
handlers based on a not up-to-date pdev->msix_enabled value.
Route the handlers directly to the requisite core routines.
Todo: hook up error interrupt handling
