The Bazel WORKSPACE file in build/kernel/kleaf is not
sufficient for our usecase. We must add a nested
workspace for host DTC build.
Add the custom workspace file here so we can link it
to the top-level via repo manifest.

Ignore the ENODEV failures returned by kernel_sendmsg(). These errors
mean either the local port has closed or the remote has gone down.
Neither of these scenarios are fatal and will eventually be handled
through packets that are later queued on the control port.
Also improve the logging messages to print the error code returned by
kernel_sendmsg().

Increase the socket recvbuf for the ns so control packets are not
dropped in heavy traffic situations. This change will not
actually set the recvbuf to INT_MAX but to the system defined rmem_max
for sockets.

If worker is not processing packets on control port fast enough,

after controller powers down and is freed when the controller
unregisters with MHI. Add a controller flag to make the

added and doorbells are rung in mission mode transition. All
event ring doorbells are rung in M0 state change transition.
Move this common code to a helper API mhi_setup_event_rings().
Pass a boolean for adding event ring elements. When this flag
is false, only ring doorbells for all event rings and do not
populate the event rings.

In case firmware request fails to find firmware at the default
location, re-try once with a fallback location. This is done by
adding fallback firmware image location in controller structure
and firmware request is sent again using fallback location.
Send a status call back to controller when re-try is done to
notify them as some features may not be available.

Move sys heap allocation code into the system_qcom_sg_buffer_alloc()
function to allow core allocation code to be used from other modules.
Additionally, move the allocation of the struct qcom_sg_buffer
out of system_qcom_sg_buffer_alloc(), so that other modules can
allocate their own buffer structs with qcom_sg_buffer as an embedded
member.
Each other module will then have dmabuf->priv pointing to the
qcom_sg_buffer member of their custom buffer struct. This is needed
to allow the qcom_sg_ops.c functions to continue working as is.
