Issue: MACSEC is not enabled in DT for eqos_1 and mgbe2_1
interfaces which makes macsec_pdata pointer to NULL.
During suspend/resume macsec_pdata pointer accessed without
NULL check which resulted in crash.
Fix:
o Add NULL pointer checks for macsec_pdata in suspend and resume.
o Remove unnecessary checks for macsec in suspend and resume.

It is possible that we received the ACK from DCE even before we
start waiting. But currently we are clearing the "complete" state
before start waiting, which may result in missed interrupt.
This patch removes the clearing of complete state before wait.
Also Adds few comments for better understanding.

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.

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.

- This also removes unreachable code in driver.

The file dce-debug.c is only used when CONFIG_DEBUG_FS is enabled.
Compilation errors occur when CONFIG_DEBUG_FS is disabled.
Moreover the function "dce_init_debug" is defined in dce-debug.c.
Since compilation of this file only occurs when debugfs is enabled,
the declaration of the function should only be done when debugfs is
enabled.
This patch fixes the compilation errors by compiling the above
mentioned file only when debugfs is enabled. Also the declaration of
"dce_init_debug" is guarded by CONFIG_DEBUG_FS since it is only used
when debugfs is enabled.

For the BOOT_COMPLETE event the worker thread was immediately returning
in an error case without releasing the worker lock. This causes a
deadlock for the next worker event that has to be processed because the
worker lock can't be acquired. Fix this bug by not returning immediately
in the error case. Instead break out of the switch case block and
release the lock at the end of the function.
