nr_free_pages is now a simple access to a global variable.  Make it a macro
instead of a function.

The nr_free_pages now requires vmstat.h to be included.  There is one
occurrence in power management where we need to add the include.  Directly
refrer to global_page_state() there to clarify why the #include was added.

The PIOE device was left out before because it muxes SDRAM pins (and
is therefore a bit dangerous to mess with) and because no existing
drivers had any use for it.

It is needed for CompactFlash, however, and now that we have a way
to protect the SDRAM pins, it can be safely added.

Bugfixes for external irq handler set_irq_type():

 - If set_irq_type() can't set the type, don't change anything!

 - It's not OK to change the flow handler as part of set_irq_type(),
   among other issues that violates spinlock rules.  Instead, we can
   call the relevant handler when we demux the external interrupts.

 - The external irq demux has no need to grab the spinlock.  And in
   fact grabbing it that way was wrong, since that code might be
   pre-empted by an irq at a different priority level, and that code
   might then have tried to grab that spinlock...
