Move the chipsetready proc entry to sysfs under a new directory guest. This
entry is used by Unisys application software on the guest to acknowledge
completion of specific events for integration purposes, but these
acknowledgements are not required for the guest to operate correctly.
The store function is simplified as well, to use scanf() instead of copying
the buffer and using strsep().

The installer entry in /proc/visorchipset/installer was composed of three
separate fields as one entry. This patch removes the proc entry and associated
functions, and creates new fields with distinct entries under sysfs in the
visorchipset/install directory. The fields are:
textid: used to send the ID of a string that should be displayed on
s-Par's automatic installation progress screen. Setting this
field when not in installation mode (boottotool was set on
the previous guest boot) has no effect.
remaining_steps: used to set the value of the progress bar on the
s-Par automatic installation progress screen. This field has
no effect if not in installation mode.
error: used to send the ID of a string that should be displayed on
s-Par's automatic installation progress screen when an error
is encountered during installation. This field has no effect
if not in installation mode.

Move the proc entry controlling the boottotool flag to procfs. The field
appears in /sys/devices/platform/visorchipset/install/boottotool.
The boottotool flag controls s-Par behavior on the next boot of this guest.
Setting the flag will cause the guest to boot from the utility and installation
image, which will use the value in the toolaction field to determine what
operation is being requested.

Move the proc entry for controlling the toolaction field to sysfs. The field
appears in /sys/devices/platform/visorchipset/install/toolaction.
This field is used to tell s-Par which type of recovery tool action to perform
on the next guest boot-up. The meaning of the value is dependent on the type
of installation software used to commission the guest.

The controlvm channel is not removable from a guest after the guest starts,
so it makes no sense to constantly check for it. Move the channel address
discovery to visorchipset_init(), and remove all of the checks for the channel

channel pointer is not valid.

The unisys drivers now properly check to make sure they are running
on the s-Par platform before they will initialize. This was fixed in
commit fcd0157ece so it is safe to allow the unisys drivers to be built.
This has been tested in the same qemu environment that originally
produced the panic and the kernel now runs as expected.

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.

Turns out these drivers like to mess around with the system even if the
hardware they control isn't present. That's not good, and people are
starting to report lots of issues with this in their build/boot testing.
So for now, let's just mark them as BROKEN, until the code gets
converted to use the proper driver model interaction (i.e. don't do
anything until the hardware is actually found in the system.)
