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.

As reported by this application note:
https://www.nxp.com/docs/en/application-note/AN5078.pdf

The software input on (SION) bit is an option to force an input
path to be active regardless of the value driven by the
corresponding module. It is used when the nature direction
of a pin depending on selected alternative function is an output,
but it is needed to read the real logic value on a pin.

The SION bit can be used in:
• Loopback: the module of a selected alternative function drives
the pad and also receives the pad value as an input
• GPIO capture: the module of a selected alternative function
drives the pin and the value is captured by the GPIO

SION bit is not necessary when the pin is configured as a peripheral
apart specific silicon bug. If an application needs to have this
set, this should be done in board file or in dts file
