Memory controller drivers for v6.4

Browse Source 
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).
