[PATCH/RFC] arm64: defconfig: Enable HyperBus support

[Geert Uytterhoeven]

Enable modular support for HyperBus, which is used on R-Car Gen3 and
Gen4 platforms.

Note that the actual Renesas RPC-IF HyperBus driver (RPCIF_HYPERBUS) is
not enabled, as it depends on MTD_CFI_BE_BYTE_SWAP.

I think we cannot just enable MTD_CFI_BE_BYTE_SWAP in a generic kernel,
as that may break other platforms.  Is that correct?

To be queued in renesas-devel for v5.20, after the above has been
resolved.
