Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI

disables this bit when it detects a range conflict, and will re-enable
it on demand when a driver allocates the BAR. Thus, the bit is no longer
a reliable indication of capability, and should not be checked. This
results in the elimination of a lot of code from drivers, and also gives
the opportunity to simplify a lot of drivers to use a helper API to set
the busmaster enable bit.

- Implement iclear methods for QUICC and SAB 82532. With r253161 in place,
this is is crucial at least for the latter.
What happens is that attaching uart(4) to scc(4) causes the SAB 82532 to
"receive" something and trigger a SER_INT_RXREADY interrupt, given that
at least fast/filter interrupts are already enabled. Prior to r253161,
uart_bus_ihand() was set up at this point and handled that condition,
i. e. read the RX FIFO and issued a Receive Message Complete.
Now, uart_bus_ihand() and uart_intr() are setup after attaching uart(4),
leaving the SER_INT_RXREADY interrupt triggered during the latter to
be handled by the iclear method. However, with that method not implement,
this in turn causes SAB 82532 to not issue any further SER_INT_RXREADY
interrupts until the RX FIFO is full again. Thus, 15 received bytes go
to nowhere, given that "the other half" of the RX FIFO is used for status
information. Hence, implementing sab82532_bfe_iclear() fixes things again.

As it turns out, MSIs are broken with 2820SA so introduce an AAC_FLAGS_NOMSI

controller or the mainboard, though. In order to be on the safe side, flag
MSIs as being broken with the latter type of controller as well. Given that
these are the only reports of MSI-related breakage with aac(4) so far and
OSes like OpenSolaris unconditionally employ MSIs for all adapters of this
family, however, it doesn't seem warranted to generally disable the use of
MSIs in aac(4).
While at it, simplify the MSI allocation logic a bit; there's no need to
