As a part of pseries_idle backend driver cleanup to make
the code common to both pseries and powernv platforms, it
is necessary to move the backend-driver code to drivers/cpuidle.
As a pre-requisite for that, it is essential to move plpar_wrapper.h
to include/asm.

plpar_get_term_char is only used once and just adds a layer
of complexity to H_GET_TERM_CHAR. plpar_put_term_char isn't
used at all so we can remove it.

This file is only exporting symbols and so should use export.h
and not module.h header. But in doing the conversion, we will
uncover that it was implicitly using errno.h via module.h:
CC arch/powerpc/platforms/pseries/hvconsole.o
arch/powerpc/platforms/pseries/hvconsole.c: In function 'hvc_put_chars':
arch/powerpc/platforms/pseries/hvconsole.c:77: error: 'EIO' undeclared (first use in this function)

Return -EAGAIN when we get H_BUSY back from the hypervisor. This
makes the hvc console driver retry, avoiding dropped printks.

Our pseries hcall interfaces are out of control:
plpar_hcall_norets
plpar_hcall
plpar_hcall_8arg_2ret
plpar_hcall_4out
plpar_hcall_7arg_7ret
plpar_hcall_9arg_9ret
Create 3 interfaces to cover all cases:
plpar_hcall_norets: 7 arguments no returns
plpar_hcall: 6 arguments 4 returns
plpar_hcall9: 9 arguments 9 returns
There are only 2 cases in the kernel that need plpar_hcall9, hopefully
we can keep it that way.
Pass in a buffer to stash return parameters so we avoid the &dummy1,
&dummy2 madness.

These are some updates from both Ryan and Arnd for the hvc_console
driver:
The main point is to enable the inclusion of a console driver
for rtas, which is currrently needed for the cell platform.
Also shuffle around some data-type declarations and moves some
functions out of include/asm-ppc64/hvconsole.h and into a new
drivers/char/hvc_console.h file.
