Drop xtensa_elf_core_copy_regs function, ELF_CORE_COPY_REGS macro, and
dump_fpu function. Define CORE_DUMP_USE_REGSET to make ELF core dumper
use regset interface.

- define struct user_pt_regs in the arch/xtensa/include/uapi/asm/ptrace.h
with the same layout as xtensa_gregset_t; make xtensa_gregset_t a
typedef;
- define REGSET_GPR regset, implement register get and set functions;
- define task_user_regset_view function and expose REGSET_GPR.

This should never have been defined in the arch tree to begin with,
and now uapi/linux/audit.h header is going to use EM_XTENSA
in order to define AUDIT_ARCH_XTENSA which is needed to implement
syscall_get_arch() which in turn is required to extend
the generic ptrace API with PTRACE_GET_SYSCALL_INFO request.

do_copy_regs, do_restore_regs, do_save_fpregs and do_restore_fpregs are
not used or implemented by xtensa, drop these declarations from the
arch/xtensa/include/asm/elf.h

The Xtensa architecture provides a global register called THREADPTR
for the purpose of Thread Local Storage (TLS) support. This allows us
to use a fairly simple implementation, keeping the thread pointer in
the regset and simply saving and restoring it upon entering/exiting
the from user space.

The linker script was including assembly macros from the coprocessor
header file that is not otherwise used by the script.

Move all header files for xtensa to arch/xtensa/include and platform and
variant header files to the appropriate arch/xtensa/platforms/ and
arch/xtensa/variants/ directories.
Moving the files gets also rid of all uses of symlinks in the Makefile.
This has been completed already for the majority of the architectures
and xtensa is one out of six missing.
