Commit 22191ac3 ("drivers/crypto/fsl: assign job-rings to
 non-TrustZone") breaks HABv4 encrypted boot support in the
following i.MX devices:

- i.MX6UL
- i.MX7S
- i.MX7D
- i.MX7ULP

For preparing a HABv4 encrypted boot image it's necessary to
encapsulate the generated DEK in a blob. In devices listed
above the blob generation function takes into consideration
the Job Ring TrustZone ownership configuration (JROWN_NS)
and can be only decapsulated by the same configuration.

The ROM code expects DEK blobs encapsulated by the Secure World
environments which commonly have JROWN_NS = 0.

As U-Boot is running in Secure World we must have JROWN_NS = 0
so the blobs generated by dek_blob tool can be decapsulated
by the ROM code.

Job-rings assignment is now handled in OP-TEE OS, this commit can
be safely reverted.

Commit 3a7c45f6 ("simple-bus: add DM_FLAG_PRE_RELOC flag to
simple-bus driver") causes some i.MX boards that were converted
to DM, such as warp7, to fail to boot.

As explained by Lukas Auer:

"With the patch, U-Boot probes the drivers for devices under simple-bus
device tree nodes in the pre-relocation device model. The default value
of CONFIG_SYS_MALLOC_F_LEN (0x400) leaves U-Boot with not enough memory to
do this, causing it to hang."

Fix this problem by providing a convenient default value for
CONFIG_SYS_MALLOC_F_LEN.

In certain i.MX devices the encrypted boot image is failing to boot.

According to AN12056 "Encrypted Boot on HABv4 and CAAM Enabled Devices"
it's necessary to pad CSF to 0x2000 and append DEK blob.

In this case the total image size in boot data structure must cover the
entire binary otherwise the dek_blob won't be copied to memory and image
won't be decrypted.

Increase CSF_SIZE to 0x4000 to avoid such issue when booting encrypted
boot images.
