At the moment the IO space limit is hardcoded to
QPCI_PIO_LIMIT = 0x10000. When accesses are performed to a bar,
the base address of this latter is compared against the limit
to decide whether we perform an IO or a memory access.
On ARM, we cannot keep this PIO limit as the arm-virt machine
uses [0x3eff0000, 0x3f000000 ] for the IO space map and we
are mandated to allocate at 0x0.
Add a new flag in QPCIBar indicating whether it is an IO bar
or a memory bar. This flag is set on QPCIBar allocation and
provisionned based on the BAR configuration. Then the new flag
is used in access functions and in iomap() function.
