Merge tag 'memory-controller-drv-6.4' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into soc/drivers

Memory controller drivers for v6.4

1. STM32 FMC2: allow using driver on all STM32MP SoCs.
2. Cleanups:
   - Atmel EBI: use preferred of_property_present() API.
   - Tegra210 MC: drop redundant variable initialization.
   - Drop redundant quotes in Devicetree bindings.
   - Remove MODULE_LICENSE in non-modules (several drivers).

* tag 'memory-controller-drv-6.4' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl:
  dt-bindings: memory-controller: Drop unneeded quotes
  memory: stm32-fmc2-ebi: depends on ARCH_STM32 instead of MACH_STM32MP157
  memory: tegra: remove redundant variable initialization
  memory: atmel-ebi: Use of_property_present() for testing DT property presence
  memory: remove MODULE_LICENSE in non-modules
  memory: tegra: remove MODULE_LICENSE in non-modules
