qseecom: Add ioctl command and QSEOS_FSM_ENCFS_REQ for fsm fde support 



For FSM fde support, new ioctl command is added to retrieve fde ce, and
pipe pair information. QSEOS_FSM_ENCFS_REQ_CMD and
QSEOS_FSM_ENCFS_REQ_RSP_CMD are added to send service command to TZ.
In the driver, ce_hw_usage_info is enhanced to support multiple instances
of fde, and pfe.
