All legacy RAS bad pages are generated in NPS1 mode, but new bad page
can be generated in any NPS mode, so we can't use retired_page stored
on eeprom directly in non-nps1 mode even for legacy data. We need to
take different actions for different data, new data can be identified
from old data by UMC_CHANNEL_IDX_V2 flag.

Before scheduling a recovery due to scheduler/job hang, check if a RAS
error is detected. If so, choose RAS recovery to handle the situation. A
scheduler/job hang could be the side effect of a RAS error. In such
cases, it is required to go through the RAS error recovery process. A
RAS error recovery process in certains cases also could avoid a full
device device reset.
An error state is maintained in RAS context to detect the block
affected. Fatal Error state uses unused block id. Set the block id when
error is detected. If the interrupt handler detected a poison error,
it's not required to look for a fatal error. Skip fatal error checking
in such cases.

Enable RAS late init if VF RAS Telemetry is supported.
When enabled, the VF can use this interface to query total
RAS error counts from the host.
The VF FB access may abruptly end due to a fatal error,
therefore the VF must cache and sanitize the input.
The Host allows 15 Telemetry messages every 60 seconds, afterwhich
the host will ignore any more in-coming telemetry messages. The VF will
rate limit its msg calling to once every 5 seconds (12 times in 60 seconds).
While the VF is rate limited, it will continue to report the last
good cached data.

Add a separate function to read badpage data during initialization.
Reading bad pages will need hardware access and cannot be done during
