This patch removes extra blank lines from the virthba header and source
files. This is the first of a set of patches that will clean up the
virthba source file. The only checkpatch issue in the header file was
the blank line warnings.

The use of __DATE__ and __TIME__ is no longer allowed in the kernel so this
commit removes those. They were once useful when the drivers were being
built externally, but now that the drivers are in the kernel the use of the
macros is redundant since the kernel already has the same information
elsewhere.
In addition, using these macros breaks the build if using gcc 4.9.0

This patch adds support for detection of s-Par firmware by checking for
the hypervisor bit in the CPU capabilities, and then querying the hypervisor
ID cpuid leaf.
This functionality will be used by the unisys drivers to determine if
they are being loaded on an s-Par platform and refuse to load if no
s-Par firmware is present.
This fixes a problem reported from upstream where a panic occurs if the
unisys drivers are loaded on a non s-Par system.

The virthba module provides access to a shared SCSI host bus adapter
and one or more disk devices, by proxying SCSI commands between the
guest and the service partition that owns the shared SCSI adapter,
using a channel between the guest and the service partition. The disks
that appear on the shared bus are defined by the s-Par configuration
and enforced by the service partition, while the guest driver handles
sending commands and handling responses. Each disk is shared as a
whole to a guest. Sharing the bus adapter in this way provides
resiliency; should the device encounter an error, only the service
partition is rebooted, and the device is reinitialized. This allows
guests to continue running and to recover from the error.
