Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.
No functional changes.

Declare rproc_ops structures as const as they are only passed as an
argument to the function rproc_alloc. This argument is of type const, so
rproc_ops structures having this property can be declared const too.

Fix to return a negative error code from the st_rproc_state() error
handling case instead of 0, as done elsewhere in this function.

In order to be able to lock a rproc driver implementations only when
used by a client, we must differ between the dereference operation of a
client and the implementation itself.
This patch brings no functional change.

syscon_regmap_lookup_by_phandle() returns either a valid pointer to
struct regmap or ERR_PTR() error value, check for NULL is invalid and
on error path may lead to oops, the change corrects the check.
