spmi: pmic-arb: block access for invalid PMIC arbiter v5 SPMI writes
The system crashes due to an access permission violation when
writing to a PMIC peripheral which is not owned by the current
ee. Add a check for PMIC arbiter version 5 for such invalid
write requests and return an error instead of crashing the
system.
