[PATCH 1/3] avr32: fix build failure

[Sudip Mukherjee <sudipm.mukherjee@gmail.com>]

While building avr32 with allmodconfig, the build used to fail with the
message:
error: implicit declaration of function 'pci_iomap'
error: implicit declaration of function 'pci_iounmap'

Create dummy pci_io{map,unmap} functions to fix the build.

Signed-off-by: Sudip Mukherjee <sudip@vectorindia.org>

Tested with defconfig, allmodconfig, allnoconfig and merisc_defconfig.
Build is at:
https://travis-ci.org/sudipm-mukherjee/parport/builds/81168845

Partial idea taken from:
78857614104a ("MIPS: Expose missing pci_io{map,unmap} declarations")
which solved a similar problem with mips.
