The powernv platform is the only one that directly accesses SCOMs. Move the support code to platforms/powernv, and get rid of the PPC_SCOM Kconfig option, as SCOM support is always selected when compiling for powernv. This also means that the Kconfig item for CONFIG_SCOM_DEBUGFS will show up in menuconfig in the platform menu, rather than at the root, which is a much better location.

This enables support for IBM Virtual Accelerator Switchboard (VAS).

VAS allows accelerators in co-processors like NX-GZIP and NX-842

to be accessible to kernel subsystems and user processes.

VAS adapters are found in POWER9 based systems.
