virtio-ccw: remove qdev_unparent in unplug routing

This patch fixes unplugging a virtio-ccw device. We no
longer need to do that in virtio-ccw since common code does now
proper handling.

Fix TAGS creation

Currently the Makefile creates TAGS for emacs with the command:
    find "$(SRC_PATH)" -name '*.[hc]' -print0 | xargs -0 etags
That works only if xargs ends up invoking etags just once.  If xargs runs
etags several times, as it will if there are enough files, then the later
invocations will overwrite the output from the earlier invocations.  This
patch uses the etags --append option to fix the bug.

hw/vexpress: Pass proc_id via VEDBoardInfo

Pass the daughterboard-specific proc_id property to the code that
creates the sysctl device via the VEDBoardInfo struct, rather than
by having the daughterboard init function write to a uint32_t*
argument. This is a cleaner way to pass the info around, and
is in line with the way we are going to handle voltage and
oscillator initialization.

hw/arm_sysctl: Handle SYS_CFGCTRL in a more structured way

The SYS_CFGCTRL register consists of separate fields
for DCC, function, site, position and device, as well
as a read/write bit. Refactor the code handling SYS_CFGCTRL
writes to make it easier to add support for functions
like SYS_CFG_OSC which support multiple device fields.
We also pull the handling out into its own function for
clarity, as there are potentially a lot of implementable
subfunctions.

hw/arm_sysctl: Implement SYS_CFG_MUXFPGA writes as a no-op

SYS_CFG_MUXFPGA allows the guest to select whether the
video output should come from the motherboard's LCD
controller or the daughterboard's one. Since QEMU doesn't
currently support selecting the video output like this,
implement as a no-op, so Linux doesn't complain about
the register not being implemented.

hw/arm_sysctl: Implement SYS_CFG_DVIMODE as a no-op

SYS_CFG_DVIMODE allows the guest to select whether the
output DVI signal is VGA, SVGA, XGA, SGA or UXGA. Since
this makes no difference to QEMU, implement writes as a
no-op so Linux doesn't complain.

qdev: Implement (variable length) array properties

Add support for declaring array properties for qdev devices.
These work by defining an initial static property 'len-arrayname'
which the user of the device should set to the desired size
of the array. When this property is set, memory is allocated
for the array elements, and dynamic properties "arrayname[0]",
"arrayname[1]"... are created so the user of the device can
then set the values of the individual array elements.

hw/arm_sysctl: Implement SYS_CFG_VOLT

Implement the SYS_CFG_VOLT registers which return the voltage
of various supplies on motherboard and daughterboard. Since
QEMU implements a perfectly stable power supply these registers
always return a constant value. The number and value of the
daughterboard voltages is dependent on the specific daughterboard,
so we use a property array to allow the board to configure them
appropriately.

hw/arm_sysctl: Implement SYS_CFG_OSC function

Implement the SYS_CFG_OSC function. Since the idea of
programmable clock rates doesn't make much sense for QEMU,
we simply allow the clock rate to be read back as written.
The number and value of the daughterboard oscillators varies
between daughterboards, so we provide an array property to
allow their reset values to be configured.
