SPARC32: fix romvec stdin/stdout field initialisation
Previously the romvec stdin/stdout ihandles were configured so that they were
set to the current stdin and stdout paths at initialisation time. Unfortunately
as stdin/stdout can be changed with the input and output words, they can end
up pointing to invalid ihandles causing a crash when trying to output to the
console.
Fix this by pointing the romvec structure to the address of the stdin/stdout
variables so that they are always in sync. Similarly we also resolve the
text path stdin/stdout variables at boot time to ensure that they will never
be stale.

[PATCH 1/2] PPC: Fix PCI configuration space address access
by Mark Cave-Ayland
This patch corrects two long-standing bugs with PPC PCI configuration space
access. Firstly fix the calculation of PCI configuration space addresses by
the PCI_ADDR macro; this was incorrectly using arch->cfg_base which is the
mapped address and has nothing to do with the PCI configuration space
address. Instead just set bit 31 to initiate a configuration cycle as per the
PCI specification.
Secondly, fix pci_config_read32() and pci_config_write16() which were
incorrectly adding the register offset to the PCI IO dataport address causing
them to write into unknown address space for registers > 0. It appears that
this only worked purely by coincidence with QEMU due to the way in which the
configuration address was calculated for an oversized PCI configuration IO
dataport MemoryRegion.

PCI: switch calculation of host PCI memory base to use an offset
Instead of using two different variables to track the absolute values of the
PCI memory base and the host memory base, change the host memory base to be
an offset which is added to the PCI memory base during conversion. As a
consequence of this, the code in pci_bus_addr_to_host_addr() can be unified
to be consistent across all architectures.
Note that this commit also renames arch->host_mem_base to arch->host_pci_base
in order to better describe its function.
