drm/xe/xe_survivability: Decouple survivability info from boot survivability

Browse Source 
On CSC runtime firmware errors that requires firmware flash through SPI,
PCODE sets the FDO mode bit in the Capability register.
Currently the survivability_info group is created only for boot
survivability.

Create survivability_info group even for runtime survivability to allow
userspace to check FDO mode sysfs.
