PDC_DEBUG, PDC_ALLOC and PDC_SCSI_PARMS were missing.
Add PDC_MODEL_GET_INSTALL_KERNEL and PDC_NVOLATILE_* subfunctions.
PDC_CONFIG is call #17, not 16. Luckily it's nowhere referenced yet.

The PDC_RELOCATE function is called by HP-UX shortly before crashing.
So, we need to handle it in qemu and thus it makes sense to add the
constant here.
Additionally add other subfunctions like PDC_MODEL_GET_PLATFORM_INFO (to
get product and serial numbers) and PDC_TOD_CALIBRATE (to calibrate
timers) too.

While working on a qemu and SeaBIOS-port to parisc, those PDC structures are
useful to have accessible from userspace.

license
Many user space API headers are missing licensing information, which
makes it hard for compliance tools to determine the correct license.
By default are files without license information under the default
license of the kernel, which is GPLV2. Marking them GPLV2 would exclude
them from being included in non GPLV2 code, which is obviously not
intended. The user space API headers fall under the syscall exception
which is in the kernels COPYING file:
NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".
otherwise syscall usage would not be possible.
Update the files which contain no license information with an SPDX
license identifier. The chosen identifier is 'GPL-2.0 WITH
Linux-syscall-note' which is the officially assigned identifier for the
Linux syscall exception. SPDX license identifiers are a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne. See the previous patch in this series for the
methodology of how this patch was researched.

The firmare in most parisc machines maintains a Page Deallocation Table (PDT)
which holds a list of physical memory addresses where hardware detected memory
errors (single bit and double bit errors).
This patch adds the missing PDC firmware calls and the logic to read the PDT
from firmware, report all current PDT entries and exclude the reported bad
memory from being used by Linux.
