ARM/ixp4xx: Move the virtual IObases
UART1, UART2 and the expansion bus config registers
are the only registers mapped in a fixed location
when using device tree.
For device tree we also want to get rid of the custom
<mach/io.h> for IXP4xx. So we need to undefine
CONFIG_NEED_MACH_IO_H. Doing that activates the fixed
mapping of the PCI IO space to PCI_IO_VIRT_BASE which
is hardcoded to 0xFEE00000 and this would collide with
the old fixed mappings.
Move the fixed virtual IO base address from 0xFEF00000
to 0xFEC00000 in order to avoid the collision.
For the OF-only boot path let's even cut the reliance
on <mach/io.h> and just hardcode the one single virtbase
we need apart from the UART, which is hardcoded in
Kconfig.debug.
