Memory controller drivers for v6.20

Browse source

1. Mediatek SMI: Fix old struct device reference leaks during error
    paths and device unbinding.
 
 2. Memory Devicetree bindings: refactor existing LPDDR bindings and add
    bindings for DDR4 SDRAM.  These will be used for example in
    stm32mp257f-ev1 DTS.
