efi/arm: Show SMBIOS bank/device location in CPER and GHES error logs

Run dmi_memdev_walk() for arch arm* as other architectures do.
This improves error logging as the memory device handle is
translated now to the DIMM entry's name provided by the DMI handle.

Before:

 {1}[Hardware Error]:   DIMM location: not present. DMI handle: 0x0038

After:

 {1}[Hardware Error]:   DIMM location: N0 DIMM_A0
