Change the condition for zeroing TPM event log address in device tree
from CFG_CORE_SEL1_SPMC to CFG_CORE_FFA. When CFG_CORE_FFA is enabled,
the device tree comes from the manifest DT which is mapped as read-only,
not from the external device tree. Attempting to zero the
tpm_event_log_addr property in the manifest DT would cause a write
permission fault exception.
The fix prevents this fault by ensuring the zeroing operation only occurs
when using the external device tree (CFG_CORE_FFA=n), where write access
is permitted.
