[PATCH] RAPIDIO: Fix idt_gen2.c build

[Ralf Baechle <ralf@linux-mips.org>]

idt_gen2.c relies that one of the header files used will include
<asm/page.h> which will define the required symbol PAGE_SIZE.  On MIPS
for example <asm/page.h> will not be included implicitly which will
result in the following build error:

  CC      drivers/rapidio/switches/idt_gen2.o
drivers/rapidio/switches/idt_gen2.c: In function ‘idtg2_show_errlog’:
drivers/rapidio/switches/idt_gen2.c:379:30: error: ‘PAGE_SIZE’ undeclared (first use in this function)
drivers/rapidio/switches/idt_gen2.c:379:30: note: each undeclared identifier is reported only once for each function it appears in

If you're ok with this patch I can put it into my next pull request for
Linux.  Thanks!
