imx8m: Add DEK blob encapsulation for imx8m
Add DEK blob encapsulation support for IMX8M through "dek_blob" command.
On ARMv8, u-boot runs in non-secure, thus cannot encapsulate a DEK blob
for encrypted boot.
The DEK blob is encapsulated by OP-TEE through a trusted application call.
U-boot sends and receives the DEK and the DEK blob binaries through OP-TEE
dynamic shared memory.
To enable the DEK blob encapsulation, add to the defconfig:
CONFIG_SECURE_BOOT=y
CONFIG_FAT_WRITE=y
CONFIG_CMD_DEKBLOB=y
