These have been using overrides for ELF_CORE_COPY_TASK_REGS and
ELF_CORE_COPY_FPREGS while the generic versions can be used instead.
Presently the pt_regs are also duplicated across elf_core_copy_regs()
and elf_core_copy_task_regs(), this switches to simply copying out
through elf_core_copy_regs() instead.

This adds a defconfig for the R2D+ target in the qemu system emulator.
Eventually it will be possible to simply use the r2d+ defconfig as it is.

All CPUs must have a sensible cpu_clk definition these days, which we can
safely use for deriving the preset loops_per_jiffy. The only odd one out
is SH-5, which hasn't been hammered in to the framework yet.

Presently this is doing a force_sig() SIGTRAP, which is already taken
care of in the generic code if no one asserts NOTIFY_STOP. Switch the
default return to NOTIFY_DONE in the case of unhandled traps, so that
the same trap may pass through to other users on the same die chain.

This fixes a problems with the set up of Linux memory:

 - When reserving memory at boot time, the code previously reserved
   the bottom page of memory, and then from one page up to the end of
   the bootmap. This had the desired effect, but was strictly speaking
   wrong, as the one page was actually whatever CONFIG_ZERO_PAGE_OFFSET
   had been set to.
