Extend the instantiate_rng() function and the corresponding CAAM job

instantiation code in line with the CAAM kernel driver.
Previously, only the first state handle was instantiated. The second
one was instantiated by the CAAM kernel driver. This works if the
kernel runs in secure mode, but fails in non-secure mode since the
kernel driver uses DEC0 directly instead of over the job ring
interface. Instantiating all RNG state handles in u-boot removes the
need for using DEC0 in the kernel driver, making it possible to use

This patch adds a sec_init call into arch_misc_init(). Doing so in

u-boot will initialise the RNG and assign ownership of the job-ring
registers to a non-TrustZone context. With recent changes by Lukas Auer to
fully initialize the RNG in sec_init() this means that u-boot will hand-off
the CAAM in a state that Linux then can use the CAAM without touching the
reserved DECO registers.
This change is safe both for the OPTEE/TrustZone boot path and the regular
non-OPTEE/TrustZone boot path.

drivers/crypto/fsl: assign job-rings to non-TrustZone
After enabling TrustZone various parts of the CAAM silicon become
inaccessible to non TrustZone contexts. The job-ring registers are designed
to allow non TrustZone contexts like Linux to still submit jobs to CAAM
even after TrustZone has been enabled.
The default job-ring permissions after the BootROM look like this for
job-ring zero.
ms=0x00008001 ls=0x00008001
The MS field is JRaMIDR_MS (job ring MID most significant).
Referring to "Security Reference Manual for i.MX 7Dual and 7Solo
Applications Processors, Rev. 0, 03/2017" section 8.10.4 we see that
JROWN_NS controls whether or not a job-ring is accessible from non
TrustZone.
Bit 15 (TrustZone) is the logical inverse of bit 3 hence the above value of
0x8001 shows that JROWN_NS=0 and TrustZone=1.
Clearly then as soon as TrustZone becomes active the job-ring registers are
no longer accessible from Linux, which is not what we want.
This patch explicitly sets all job-ring registers to JROWN_NS=1 (non
TrustZone) by default and to the Non-Secure MID 001. Both settings are
required to successfully assign a job-ring to non-secure mode. If a piece
of TrustZone firmware requires ownership of job-ring registers it can unset
the JROWN_NS bit itself.
This patch in conjunction with a modification of the Linux kernel to skip
HWRNG initialisation makes CAAM usable to Linux with TrustZone enabled.
