Subject: [PATCH 3/5] efi/arm: Show SMBIOS bank/device location in cper and ghes error logs

From: Marcin Benka <mbenka@...vell.com>

Run dmi_memdev_walk() for arch arm* as other archs 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
