PD#SWPL-124965 Problem: Need key ladder/table driver for kernel5.15 The KT driver needs to be separated from the descrambler. New APIs are needed for the KT driver. Solution: Create a seckey driver. Verify: S5 KT/KL with DMA T3 METACAS with Descramble T5W Change-Id: Id058e64f99918b66e79d24647880f999f55ca13a Signed-off-by: Doosan Baek <doosan.baek@amlogic.com>
