Renesas ARM64 Based SoC Defconfig Updates for v4.14

* compile ak4613 and renesas sound as modules

  This is intended to reduce the size of a kernel image compiled
  using the defconfig. This is timely as it brings the kernel image
  back below the size that can be booted in my environment, a limit
  it crept over in v4.13-rc1.
arm64: defconfig: compile ak4613 and renesas sound as modules

Compile the renesas sound and ak4613 drivers as modules to reduce the ARM64
kernel size. These modules are currently only used by Renesas platforms so
there should little risk of negative impact of this change on other users.
