s390/comments: unify copyright messages and remove file names
Remove the file name from the comment at top of many files. In most
cases the file name was wrong anyway, so it's rather pointless.
Also unify the IBM copyright statement. We did have a lot of sightly
different statements and wanted to change them one after another
whenever a file gets touched. However that never happened. Instead
people start to take the old/"wrong" statements to use as a template
for new files.
So unify all of them in one go.

[SCSI] zfcp: support for hardware data router
FICON Express8S supports hardware data router, which requires an
adapted qdio request format.
This part 2/2 exploits the functionality in zfcp.

[S390] qdio: Split SBAL entry flags
The qdio SBAL entry flag is made-up of four different values that are
independent of one another. Some of the bits are reserved by the
hardware and should not be changed by qdio. Currently all four values
are overwritten since the SBAL entry flag is defined as an u32.
Split the SBAL entry flag into four u8's as defined by the hardware
and don't touch the reserved bits.

[SCSI] zfcp: Introduce experimental support for DIF/DIX
Introduce support for DIF/DIX in zfcp: Report the capabilities for the
Scsi_host, map the protection data when issuing I/O requests and
handle the new error codes. Also add the fsf data_direction field to
the hba trace, it is useful information for debugging in that area.
This is an EXPERIMENTAL feature for now.

[SCSI] zfcp: Cleanup QDIO attachment and improve processing.
Some definitions and structures in the zfcp QDIO processing are
improved by the removal of not required variables and processing steps.
I addition the naming of some variables is changed to make their purpose
more clear.

[SCSI] zfcp: Cleanup function parameters for sbal value.
A lot of functions require the amount of SBALs as one of their
parameter which is most times invariable. Therefore remove this
parameter and set the SBAL value explicitly if a non standard value is
required. In addition the warning message "oversized data" is
replaced with a BUG_ON() statement assuring the limits defined and
requested by zfcp.

[SCSI] zfcp: Report scatter-gather limits to SCSI and block layer
Instead of dealing with large segments in the scatter-gather lists in
zfcp_qdio.c, report the limits to the upper layers. With these limits
in place, the code for mapping large data blocks to multiple sbales
can be removed.

[SCSI] zfcp: Introduce header file for qdio structs and inline functions
Move the qdio related structs and some helper functions to a new
zfcp_qdio.h header file. While doing this, rename the struct
zfcp_queue_req to zfcp_qdio_req to adhere to the naming scheme used in
zfcp. This allows a better seperation of the qdio code and inlining
the helper functions will save some function calls.
