With CFG_CORE_HUK_SUBKEY_COMPAT=y, tee_fs_init_key_manager() and
consequently tee_otp_get_die_id() get executed earlier than the

drivers: caam: add JR interrupt only if CFG_CAAM_ITR=y

Adding the JR interrupt in the OPTEE CAAM driver, even if not used in
OPTEE, prevents the Linux CAAM driver from using the JR interrupt on
platforms sharing the same line of interruption for all job rings.

To dequeue job from the job ring, the Linux CAAM driver would pull the
number of jobs done from the output ring slot full register.

The fix is to add the JR interrupt only if CFG_CAAM_ITR=y. This
allows the Linux CAAM driver to dequeue jobs faster than polling from
a register.

drivers: caam: fix function definition when CFG_CAAM_NO_ITR=y

There is a bug in the CAAM JR interruption enablement logic. When
CFG_CAAM_NO_ITR=y, the JR interruptions are used and when
CFG_CAAM_NO_ITR=n, the JR interruptions are not used.

Even with this wrong logic, the CAAM is still able to enqueue jobs.
When no JR interruptions are received, the CAAM will manually dequeue
jobs from the jobring by checking the number of jobs done in the output
ring slots full register.

CAAM JR interruptions are not mandatory for the CAAM to work properly
but it makes the dequeuing faster than polling the output ring slot full
register.

To avoid confusion, replace CFG_CAAM_NO_ITR with CFG_CAAM_ITR. The
CFG_CAAM_ITR is enabled by default and platforms not using the JR
interruptions would have this flag disabled instead.

drivers: tzc380: fix the lockdown range register value

This register controls the range of regions that are locked down.
The number of regions to lockdown are defined in [1]:
lockdown_range[3:0] and its value goes from b0000 to b1111.

If the goal of tzc_regions_lockdown() is to lock all regions supported
by the platforms, then the value of lockdown_range[3:0] should be equal
to no_of_regions[3:0] of the configuration register [2].

Currently, tzc.num_regions is used to defined the lockdown range which
is incorrect because it has been incremented during initialization.
Fix the issue by decrementing tzc.num_regions before the configuration
of lockdown_range[3:0].
