The PRCMU driver is only available on the UX500 platforms so building
on x86_64 does not make sense.

Ola/Mark: a simple patch like this should solve the issue I think?

diff --git a/sound/soc/ux500/Kconfig b/sound/soc/ux500/Kconfig

 menuconfig SND_SOC_UX500

        help
                Say Y if you want to enable ASoC-support for
                any of the Ux500 platforms (e.g. U8500).


But it seems it has a wider dependency on some MOP500 board
stuff being merged first, which is more of a problem I think, part
of that is pending in the Ux500 tree.
