Arm FF-A fixes for v6.8

Quite a few fixes addressing issues around missing RW lock initialisation
in ffa_setup_partitions(), missing check for xa_load() return value,
use of xa_insert instead of xa_store to flag case of duplicate insertion.
It also simplifies ffa_partitions_cleanup() with xa_for_each() and xa_erase()
instead of xa_extract() and kfree(). Finally it includes fixes around
handling of partitions setup failures during initialisation.
