19fb93666d platform: tegra: dce: Use conftest 
Instead of relying on kernel version to determine if the 'tegra_ivc'
structure has a member that is of type 'struct iosys_map', add a compile
time test to the conftest.sh script to determine this at compile time
for the kernel being used. This is beneficial for working with 3rd party
Linux kernels that may have back-ported upstream changes into their
kernel and so the kernel version checks do not work.

2ea5632398 platform: dce: reset condition variable after use 
Once we complete EVENT_ID_DCE_BOOT_COMPLETE_RECEIVED event handling, it
doesn't reset the complition variable. Which causes
dce_wait_interruptible to exit early without waiting in next cycle.

This patch fixes the same by resetting complition variable after use for
EVENT_ID_DCE_BOOT_COMPLETE_RECEIVED.

5d5463b60f platform:dce: notify dce after state ack 
The current code doesn't notify DCE IPC after DCE IPC is in ACK state
Current Flow:

         CPU                      DCE
1: tegra_ivc_init               ---------
2: DCE_ADMIN_CMD_IPC_CREATE     tegra_ivc_init
3:     ---------                tegra_ivc_channel_reset
                                    dce:SIVC_STATE_SYNC
                                    cpu:ESTABLISHED
4: tegra_ivc_reset
       dce:SIVC_STATE_SYNC      ---------
       cpu:SYNC
5: Notify()                     tegra_ivc_channel_notified
                                    dce:SIVC_STATE_ACK
                                    cpu:SYNC
6: tegra_ivc_notified           ---------
       dce:SIVC_STATE_ACK
       cpu:ESTABLISHED

After Step 6 DCE state is in ACK state and CPU state is in ESTABLISHED
state. As there is no further cpu->dce notification in RM_NOTIFY
channel, dce state stays in the "ACK" state and any attempt to send msg
on RM_NOTIFY channel from dce->cpu fails.

This patch notifies dce after step-6, So dce channel is also in the
"ESTABLISHED" state.

If steps 3-6 get executed in CPU before Step 5 in DCE gets a chance
to execute (DCE is slow), the CPU IPC state will change to "established".
Now when step 5 will execute in DCE, it'll see the CPU state as
"established" so, It'll make the DCE state also "established".
That's how it's working today.

bb8fc06951 platform: dce: fix async msg read prints 
While MST is used, We get two async msgs from DCE and schedule 2 worker
threads, But during processing (dce_client_process_event_ipc) of these
messages, We are processing all the pending messages in one go. So,
while the second worker thread is scheduled, there is no new message
to read.

This Patch fixes the loop to try reading only when there is a new msg to
read. Also convert info print to debug, to avoid print noise.

- when there are multiple async events back to back from DCE with very
short time gap between 2 events(for example, in case of DP MST,
2 heads could be sending flip event notification back to back at
almost same time), there is a possibility of 2nd async event getting
processed very late when shared mailbox register is set to zero as part
of processing 1st async event and before processing of 2nd async event.
- current change fixes it by processing all pending IVC frames for IPC
channel when processing an async event.
- change few error logs to info logs as these are not actually errors.

b982595c51 platform: tegra: dce: retry interrupted rpc wait 
currently dce_client_ipc_wait_rpc function waits with
"wait_event_interruptible". And if process is interrupted, it leads
to RPC failure as "dce_ipc_send_message_sync" will try to read RPC msg
when there is no msg to read yet.

This CL make change to restart/retry wait if condition variable is not
signaled by "dce_client_ipc_wakeup"
