Merge tag 'memory-controller-drv-5.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into arm/drivers

Memory controller drivers for v5.19, part two

1. Cleanup: simplify platform_get_resource() calls by using
   devm_platform_get_and_ioremap_resource() helper.
2. OMAP: allow building omap-gpmc as module and make it visible (it is
   not selected by platform anymore).

* tag 'memory-controller-drv-5.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl:
  memory: omap-gpmc: Allow building as a module
  memory: omap-gpmc: Make OMAP_GPMC config visible and selectable
  memory: renesas-rpc-if: simplify platform_get_resource_byname()
  memory: brcmstb_dpfe: simplify platform_get_resource_byname()
  memory: tegra: mc: simplify platform_get_resource()
  memory: ti-emif-pm: simplify platform_get_resource()
  memory: ti-emif: simplify platform_get_resource()
  memory: emif: simplify platform_get_resource()
  memory: da8xx-ddrctl: simplify platform_get_resource()
