This patch adds runtime pm support for the bundle core. Unbound bundle
devices are always deactivated. During probe, Runtime PM status is set
to enabled and active and the usage count is incremented. If the driver
supports runtime PM, it should call pm_runtime_put() in its probe
routine and pm_runtime_get_sync() in remove routine as bundle needs to
be resume before it can be deactivated.

Add connection flag to indicate that a connection has high priority.
For the SVC and control connections this may be used by the host-device
driver as a hint to allocate dedicated DMA channels or to use polling to
avoid message congestion.
We also allow drivers to set this flag on their connections, even though
we currently have no use case for this (and the host-device driver is
again free to ignore it).
Note that this mechanism can be used to indicate also high-bandwidth
connections (e.g. wanting larger buffers or dedicated endpoints), but
that that should be done using a separate high-bandwidth flag rather
than overloading the high-priority flag.

step.

The greybus SVC core handles events from the SVC serially today. In some
cases the SVC operations may take too long, for example trying to
activate a dummy interface. If another interface receives a mode-switch
mailbox event in that time, the SVC core wouldn't be able to process it
in quickly enough and bootrom driver will print following error:
bootrom 1-3.3.1: Timed out waiting for Interface Mode Switch from the Module
This can be reproduced easily by attaching a 2x2 module along with any
other normal module like camera or speaker, and doing a unipro_reset
from userspace.
The logs suggest this time to be around 6-7 seconds in most of the
cases. Attaching multiple modules with dummy interfaces may make this
worst.
Lets increase the timeout from 5 to 10 seconds for now, also add a FIXME
for the same.
