fw_cfg: the I/O port variant expects little-endian

The I/O port variant of fw_cfg is used by sparc64, which is a big-endian machine.
Firmware swaps bytes before sending them to fw_cfg, so we need to unswap them in
the device.

This is only used on sparc64 and on (little-endian) x86, so it does not affect...

ds1225y: Drop bogus qdev field from NvRamState

spapr-rtas: add CPU argument to RTAS calls

RTAS is a hypervisor provided binary blob that a guest loads and
calls into to execute certain functions. It's similar to the
vsyscall page in Linux or the short lived VMCI paravirt interface
from VMware.

The QEMU implementation of the RTAS blob is simply a passthrough...

fw_cfg: add API to find FW cfg object

Remove some code duplication by adding a
function to look up the fw cfg file.
This way, we don't need to duplicate same strings everywhere.
Use by both fw cfg and pvpanic device.

fw_cfg: fw_cfg is a singleton

Make sure we only have a single instance ever:

useless anyway.
