Currently the ISA devices that are part of the VIA south bridge,
superio chip are wired up by board code. Move creation of these ISA
devices to the VIA ISA bridge model so that board code does not need
to access ISA bus. This also allows vt82c686b-superio to be made
internal to vt82c686 which allows implementing its configuration via
registers in subseqent commits.

Similar to the SMBus io registers there is a power management io range
that is set via similar base address reg and enable bit. Some handling
of this was already there but with several problems: using the wrong
registers and bits, wrong size range, not acually updating mapping and
handling reset correctly, nor emulating any of the actual io
registers. Some of these errors are fixed up here.
After this patch we use the correct base address register, enable bit
and region size and allow guests to map/unmap this region, but we
still don't emulate any of the registers in this range.
PMD notes regarding the Configuration Space Power Management Registers:
- 0x40 General Configuration 0
- 0x41 General Configuration 1
. Bit 7: I/O Enable for ACPI I/O Base
- 0x48 Power Mgmt I/O Base
. Bit 0: Always set
. Bits 7-15: Power Management I/O Register Base Address

Previously just an empty RAM region was mapped on realize, now we add
an empty io range logging access instead. I think the pm timer should
be hooked up here but not sure guests need it. PMON on fuloong2e sets
a base address but does not seem to enable region; the pegasos2
firmware pokes some regs but continues anyway so don't know if
anything would make use of these facilities. Therefore this is just a
clean up of previous state for now and not intending to fully
implement missing functionality which could be done later if some
guests need it.

The base address of the SMBus io ports and its enabled status is set
by registers in the PCI config space but this was not correctly
emulated. Instead the SMBus registers were mapped on realize to the
base address set by a property to the address expected by fuloong2e
firmware.
Fix the base and config register handling to more closely model
hardware which allows to remove the property and allows the guest to
control this mapping. Do all this in reset instead of realize so it's
correctly updated on reset.
