Some old ASICs might not implement/require get_dig_frontend helper; in this scenario, we can have a NULL pointer exception when we try to call it inside vbios disable operation. For example, this situation might happen when using Polaris12 with an eDP panel. This commit avoids this situation by adding a specific get_dig_frontend implementation for DCEx.

In Virtualization case, when one VF is sending too many FLR requests, hypervisor would stop responding to this VF's request for a long period of time. This is called event guard. During this period of cooling time, guest driver should wait instead of doing other things. After this period of time, guest driver would resume reset process and return to normal. Currently, guest driver would wait 12 seconds and return fail if it doesn't get response from host. Solution: extend this waiting time in guest driver and poll response periodically. Poll happens every 6 seconds and it will last for 60 seconds. v2: change the max repetition times from number to macro. Signed-off-by:
