This change uses GPIO IRQ instead of IOAPIC for GPP_A0 pad which is
the interrupt line for sx9310. This is required because IRQ# used by
GPP_A0 is allocated for PIRQ which does not allow IRQ# sharing.
Additionally, this change also configures GPP_A6 for GPIO IRQ. GPP_A6
is currently unused in the devicetree.

Element Self Description register (ESD) [23:16] is R/WO, so let
write the ESD.CID when we start ich7_setup_root_complex_topology.
This value is also used to program the R/WO 'Target Component ID'
registers of RPxD and HHD.
Once it is done, no need to rewrite on them as they become RO.
(For more information, please see ICH7 datasheet page 271.)
Tested done on 945G-M4 using printk before and after writing.
Before this change, writing on those registers had no effect:

lsbpos and msbpos have incorrect behaviour when given 0.
lsbpos(0) returns 8, and msbpos(0) hangs. The latter is
because the check i >= 0 is always true for an unsigned
integer, causing it to loop indefinitely (this was flagged
by Coverity).
0 doesn't have a lsb or msb position, so we change both
functions to return -1 in this case to indicate an error.
The code already guards against calling these functions
with 0, but we make this more explicit to prevent errors
in the future.

The effect of pointer aliasing on writes is that any data on CPU
registers that has been resolved from (non-const and non-volatile)
memory objects has to be discarded and resolved. In other words, the
compiler assumes that a pointer that does not have an absolute value
at build-time, and is of type 'void *' or 'char *', may write over
any memory object.
Using a unique datatype for MMIO writes makes the pointer to _not_
qualify for pointer aliasing with any other objects in memory. This
avoid constantly resolving the PCI MMCONF address, which is a derived
value from a 'struct device *'.
