Using IS_ERR_OR_NULL() together with PTR_ERR() is a typical mistake. If
the value is NULL, then the function will return 0 instead of a proper
return code. Moreover dpu_hw_vbif_init() function can not return NULL.
So, replace corresponding IS_ERR_OR_NULL() call with IS_ERR().

The commit 6874f48bb8 ("drm/msm: make mdp5/dpu devices master
components") changed the MDP5 driver to look for the interconnect paths
in the MDSS device rather than in the MDP5 device itself. This was left
unnoticed since on my testing devices the interconnects probably didn't
reach the sync state.
Rather than just using the MDP5 device for ICC path lookups for the MDP5
devices, introduce an additional helper to check both MDP5/DPU and MDSS
nodes. This will be helpful for the MDP5->DPU conversion, since the
driver will have to check both nodes.

We have recently enabled resume flow based on notifications.
These notifications are sent by the FW when completing the resume flow.
From IWL_DEVICE_FAMILY_AX210 the resume flow is triggered by the
transport layer on iwl_trans_d3_resume.
On IWL_DEVICE_FAMILY_22000 and earlier we trigger the resume flow by
sending the D0I3 command.
Currently, we are waiting for the notifications before sending the
command, the notifications won't be sent by the FW since there is no
resume trigger to piggyback on.
Send the command before starting the wait flow to fix it.

The wowlan info notification is quite big.
(~750 bytes without the wake packet itself).
The max FW notification size is ~2K.
There might be cases where the wake packet gets truncated because of
this limit.
Separating the wake packet from the wowlan info notification allows us to
get more data without trimming it.
Note: we currently limit the wake packet to 1600 bytes.

IMR (Isolated Memory Regions) is a mechanism to protect memory regions
from unwarranted access by agents in the system that should not have access
to that memory.
When IMR is enabled, pages in the DRAM will be located within the IMR
memory space, accessible only by the device.
As a side effect, during S4 (a.k.a hibernate) the IMR memory space
is not retained.
While the DRAM is saved to the disk and restored by the OS upon resume,
the IMR, which is hidden from the OS neither saved upon suspend nor
restored upon resume.
As a consequence of the above, it turned out that commands cannot
be sent as part of the resume flow, and so after ending
d3 the FW needs to use notifications instead of cmd-resp.
The resume flow becomes asynchronous, with a series
of notifications, starting with wowlan_info_notif, through
wowlan_pkt_notif and complete the resume flow by d3_end_notif.
This patch adds the support for wowlan info notification.
The wake packet has been removed from the wowlan info struct
and will be handled in a dedicated notification.
