[PATCH] FRV: Make the FRV arch work again

The attached patch implements a bunch of small changes to the FRV arch to
make it work again.

It deals with the following problems:

 (1) SEM_DEBUG should be SEMAPHORE_DEBUG.

 (2) The argument list to pcibios_penalize_isa_irq() has changed.

 (3) CONFIG_HIGHMEM can't be used directly in #if as it may not be defined.

 (4) page->private is no longer directly accessible.

 (5) linux/hardirq.h assumes asm/hardirq.h will include linux/irq.h

 (6) The IDE MMIO access functions are given pointers, not integers, and so
     get type casting errors.

 (7) __pa() is passed an explicit u64 type in drivers/char/mem.c, but that
     can't be cast directly to a pointer on a 32-bit platform.

 (8) SEMAPHORE_DEBUG should not be contingent on WAITQUEUE_DEBUG as that no
     longer exists.

 (9) PREEMPT_ACTIVE is too low a value.
