Everything using standard isa I/O ports and IRQ windup is considerd
being an actual isa device. That are all serial_init() users except
mips_mipssim() which seems to have a non-standard IRQ windup.
baud rate is fixed at 115200 now as no caller passed in something else.

isa-fdc is completely qdev-ified with this patch applied, all
configuration uses properties.
sysbus-fdc needs dma_channel config fixed. There is only one user
(mips_jazz) which uses dma channel 0. Can anyone knowing this
platform suggest how to deal with it? Is hardcoding fine?

Allow adding unconnected host drives by specifying if=none like it is
possible with -drive. They can be put in use with drive attributes,
like this:
drive_add dummy if=none,id=mydisk,file=/some/disk.img
device_add virtio-blk-pci,drive=mydisk
which is the monitor aequivalent to these command line switches:
-drive if=none,id=mydisk,file=/some/disk.img
-device virtio-blk-pci,drive=mydisk

Changes:
* drive_uninit() wants a DriveInfo now.
* drive_uninit() also calls bdrv_delete(),
so callers don't need to do that.
* drive_uninit() calls are moved over to the ->exit()
callbacks, destroy_bdrvs() is zapped.
* setting bdrv->private is not needed any more as the
only user (destroy_bdrvs) is gone.
* usb-storage needs no drive_uninit, scsi-disk will
handle that.

Adds device_add and device_del commands. device_add accepts accepts
the same syntax like the -device command line switch. device_del
expects a device id. So you should tag your devices with ids if you
want to remove them later on, like this:
device_add pci-ohci,id=ohci
device_del ohci
Unplugging via pci_del or usb_del works too.

Two bug fixes:
* When freeing a device we unregister even stuff we didn't register in
the first place because the ->init() callback failed.
* When freeing a device with child busses attached, we fail to zap the
child bus (and the devices attached to it).

Switch RTC emulations to the new host_clock instead of vm_clock by
default. This has the advantage that the emulated RTC will follow
automatically the host time while it might be tuned via NTP. vm_clock
can still be selected by passing '-rtc clock=vm' on the command line.
Note that some RTC emulations (at least M48T59) already use the host
time unconditionally while others (namely MC146818) do not. This patch
introduces the required infrastructure for selecting the base clock but
only converts MC146818 for now.

If the user issues one of the following commands to the Monitor:
pci_add pci_addr=auto nic model=None
pci_add pci_addr=auto nic model=?
QEMU will exit, because the function used to perform sanity
checks (qemu_check_nic_model_list()) exits on error.
This function is used by the startup code, where it makes
sense to exit on error, but in the Monitor it doesn't.
Changing qemu_check_nic_model_list() to not exit on error
is not possible though, as it's used by the board init
code (the PC one), where all board specific code must have
void return.
The way I've chosen to fix this was to introduce a new function
called pci_nic_supported(), which checks if the NIC is supported
and returns true or false accordingly.
The new function is used only by the Monitor, it performs the
necessary check and returns an error in case the NIC is not
supported, thus qemu_check_nic_model_list()'s exit is never trigged.
The following should be observed:
1. Only the specified NIC is checked, the default one is assumed
to be supported
2. The NIC query command (model=?) won't work with pci_add, the
right way to do this with the Monitor is to add a new command

The qdev_gpio conversion of 343ec8e caused come polarity mismatch of key
event pins and left an overly complex solution behind. Take this chance
and refactor the GPIO input system of the Musicpal, moving it closer to
reality:
- Instantiate all 32 GPIO input pins and do the routing only via
qdev_connect_gpio_out.
- Implement IMR and IER registers. They manage the GPIO pin IRQ. IMR
seems to enable IRQs on rising edges, IER on falling ones. At least
this matches what the Musicpal fireware require.
- Move key pin logic inversion from the GPIO layer to musicpal_key.
