Subject: [PATCH v4 2/6] arm64: override generic version of early_init_dt_add_memory_arch()

From: Ard Biesheuvel <ard.biesheuvel@...aro.org>

Override the __weak early_init_dt_add_memory_arch() with our own
version. We need this in a subsequent patch to make the handling of
the memory nodes conditional on whether we are booting via UEFI or
not. Note that for now, all that our version does is invoke the generic
implementation.
