Enable survivability mode if supported and configfs attribute is set.
Enabling survivability mode manually is useful in cases where pcode does
not detect failure, validation and for IFR (in-field-repair).
To set configfs survivability mode attribute for a device
echo 1 > /sys/kernel/config/xe/0000:03:00.0/survivability_mode
The card enters survivability mode if supported
v2: add a log if survivability mode is enabled for unsupported
platforms (Rodrigo)
