Subject: [PATCH 1/2] arm64: defconfig: Switch SOUND to module

Sound drivers are not essential to boot boards or mount rootfs,
therefore in effort to reduce the size of kernel image (and boot images)
switch the ASoC drivers to modules to decrease the size:

  vmlinux: 152864 kB -> 154528 kB
  Image: 39391 kB -> 39067 kB

No difference in resulting include/generated/autoconf.h, except making
modules: SND_SOC_SAMSUNG, SND_SOC_SDCA_OPTIONAL, SND_SOC_APPLE_MCA,
SND_TIMER, SND_COMPRESS_OFFLOAD, SND_PCM, SND_SOC_SOF_OF and
SND_DMAENGINE_PCM.

Suggested-by: Geert Uytterhoeven <geert@...ux-m68k.org>
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

If patches are fine, I will take them via Samsung SoC.
