[PATCH] ARM: at91: resurrect mach-at91/include/mach/io.h

[manabian at gmail.com]

From: Joachim Eastwood <joachim.eastwood at jotron.com>

Commmit 4d5fc58dbe34b78 "ARM: remove bunch of now unused mach/io.h files"
removed the at91 io.h header. This makes pata_pcmcia when used with at91_cf
fail on ioport_map in pcmcia_init_one.

Adding io.h and NEED_MACH_IO_H makes my CF card work again.

Signed-off-by: Joachim Eastwood <joachim.eastwood at jotron.com>

If there is better/correct way to solve the problem please disregard this
patch.
