The neuron channels may init and probe before the secondary vm is
loaded and the resources queried from resource manager. This results
in either a blocking call or EAGAIN returned when sending a doorbell.
Move the msgq_init call from the probe to the channel sync thread. This
will ensure the init thread can continue if the doorbell send api needs
to block or busywait loop.

Currently, doorbell registration fails if a client driver attempts to
probe before the doorbell probe since data structures are not
initialized. Add an initialized flag which registration functions can
check if data structures are initialized.
Doorbell RX registration also fails if done before cap table is
populated since RX IRQ is not yet known and RX registration attempts to
register IRQ handler. IRQ registration should happen when populating the
doorbell capabilities regardless of whether a client has registered.

Currently, the cap-ids for doorbells are initialized to 0. However, 0 is
a valid value for cap-id. Instead, initialize cap-ids to HH_CAPID_INVAL
in the doorbell driver.

RM-VM(Resource Manager) send various vm status notifications(INIT/READY/
RUNNING etc) back to primary VM while PIL loader is loading the VM
images. Listern to these notifications and make a call to get the
hypervisor resources to configure doorbell and message queues.

VMs need to make GET_HYP_RESOURCE call to get resource information (dbl,
msgqs) associated between VMs. If the caller VM want to get resources
associated with another VM, caller VM has to supply the VMID of the
end point. Add support to get hypervisor resources.

Haven hypervisor provides RM dt entries in a slightly different format
than has been used. Namely: the compatible string, capids are now
described by "reg" property, VMID/owner vmid is in a sibling DT node,
and names of some properties are changed. Thus, update RM driver to
parse accordingly. Common message queue dt parsing was moved into the
msgq driver helper function "hh_msgq_probe".

On SSR, FW writes hang data in the carved out region from
existing DDR memory, the platform driver copies the hang
event data from the fixed offset to local buffer and sends
the buffer and length to host driver via CNSS_HANG_EVENT
event.

MHI reset is triggered as part of EP shutdown. Shutdown
is blocked until MHI RESET bit is cleared in MHI CTRL reg.
There is a possibility of PCIe link going down during this
time. Since MHI RESET bit never gets cleared after 2 sec
wait_event_timeout reads the MHI CTRL reg and this results
into a memory abort. Fix this issue by using a boolean flag
as condition in wait_event_timeout. This flag is set when
MHI reset is triggered and cleared when reset is done.
