remoteproc: stm32: fix incorrect optional pointers
commit fb2bdd32b231b70e6a3f1054528692f604db25d8 upstream.
Compile-testing without CONFIG_OF shows that the of_match_ptr() macro
was used incorrectly here:
drivers/remoteproc/stm32_rproc.c:662:34: warning: unused variable 'stm32_rproc_match' [-Wunused-const-variable]
As in almost every driver, the solution is simply to remove the
use of this macro. The same thing happened with the deprecated
SIMPLE_DEV_PM_OPS(), but the corresponding warning was already shut
up with __maybe_unused annotations, so fix those as well by using the
correct DEFINE_SIMPLE_DEV_PM_OPS() macros and removing the extraneous
__maybe_unused modifiers. For completeness, also add a pm_ptr() to let
the PM ops be eliminated completely when CONFIG_PM is turned off.
