[PATCH 3/3] ARM: ixp4xx: move indirect I/O into common-pci.c

Arnd Bergmann [off-list ref] writes:

The pointer comparison in is_pci_memory() confuses gcc, so it
starts throwing bogus warnings about the use of possibly uninitialized
variables:

drivers/ata/ahci_qoriq.c: In function 'ahci_qoriq_hardreset':
arch/arm/include/asm/io.h:101:2: error: 'px_is' may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/crypto/ixp4xx_crypto.c: In function 'aead_perform':
drivers/crypto/ixp4xx_crypto.c:1072:5: error: 'lastlen' may be used uninitialized in this function [-Werror=maybe-uninitialized]

The code is that gets warned about is correct, and we should not warn
about this. Moving the code into a .c file makes the object files
smaller and avoids the warnings.
