Memory controller drivers for v5.14

Several small fixes and cleanups for stm32, atmel, pl353, renesas-rpc,
TI emif and fsl_ifc.

* tag 'memory-controller-drv-5.14' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl:
  memory: emif: remove unused frequency and voltage notifiers
  memory: fsl_ifc: fix leak of private memory on probe failure
  memory: fsl_ifc: fix leak of IO mapping on probe failure
  MAINTAINERS: memory: cover also header file
  memory: renesas-rpc-if: correct whitespace
  memory: pl353: Fix error return code in pl353_smc_probe()
  memory: atmel-ebi: add missing of_node_put for loop iteration
  memory: stm32-fmc2-ebi: add missing of_node_put for loop iteration
