platform: generic/andes: pair non-retentive CSR save/restore with a flag

Browse Source 
The restore was gated on sbi_init_count() and the current sleep type,
which is only a proxy for "did this hart actually save its CSRs". Track
it explicitly instead, so restore is self-guarding and the call site
needs no conditions.
