v7a: update barebox to v2023.09.0 -> v2023.12.0

This lets us drop two patches that fixed issues with v2023.09.0.
This update also enables some options that are useful for the hardware
we support:

  - on STM32MP1, support for the NAND controller is enabled
  - on STM32MP1, we enable HWRNG and stack protector support

The latter could be enabled universally for all platforms that are no
size constrained, but it prints an ugly error message if there's no
HWRNG as using the fixed fallback canary is insecure. We'll just
postpone enabling stack protector on other platforms until we enable
HWRNG support there.

-Subject: [PATCH] remoteproc: stm32: fix typo in Kconfig symbol
-
-The Kconfig symbol for enabling support for the ARM Secure Monitor Call
-Calling Convention if CONFIG_ARM_SMCCC and not CONFIG_ARM_SMCC, but the
-latter is checked with IS_ENABLED() in the driver. Fix the typo.

-Subject: [PATCH] remoteproc: stm32: fix breakage after DT sync with upstream
-
-Once more, a device tree sync with Linux breaks a barebox driver.
-
-This time, the STM32 remoteproc driver ported from Linux was broken by
-the upstream stm32mp151.dtsi removing the st,syscfg-tz property.
-
-This property is only needed for the SiP secure monitor call case,
-but was so far always specified and the driver required its presence,
-even if it went unused.
-
-The Linux driver has since removed this hard requirement and added a new
-third way to do co-processor reset: Besides direct access to hardware
-and Silicon Provider specific secure monitor call, there's also support
-for doing it over SCMI now.
-
-Sync that part with the Linux driver to fix following boot-time error
-message:
-
-  ERROR: stm32-rproc 10000000.m4@10000000.of: failed to get tz syscfg
