- simplify the code flow of find_unisys_acpi_oem_table()
- move ACPI methods into one #ifdef block
- remove 0/NULL initialization of statics
- simplify/standardize printouts
- update copyrights

Impact: cleanup
In the subarch times there were a number of externs between
various bits of the ES7000 code. Now that there's a single
es7000-platform support file, the externs can be removed and
the functions can be changed the statics.
Beyond the cleanup factor, this also shrinks the size of the
kernel image a bit:

There were multiple definitions of apicid_cluster() scattered around
in APIC drivers - but the definitions are equivalent to the already
existing generic APIC_CLUSTER() method.
So remove apicid_cluster() and change all users to APIC_CLUSTER().

Reduce the number of include files to worry about.
Also, most of the users of APIC facilities had to
include genapic.h already, which embedded apic.h,
so the distinction was meaningless.

For those in the init namespace, while we're waiting to remove
the sysfs entry for the uid the uid is still hashed, and
alloc_uid() may re-grab that uid without getting a new
reference to the user_ns, which we've already put in free_user
before scheduling remove_user_sysfs_dir().

ASoC supports both explicit codec drivers for AC97 devices and a simple
driver which uses the standard ALSA AC97 framework for codec support.
When used with the generic AC97 codec support that will provide the
ad hoc AC97 device for drivers like touchscreens to attach to so the
core shouldn't do so.
