powerpc/vas: Move VAS API to book3s common platform 



The pseries platform will share vas and nx code and interfaces
with the PowerNV platform, so create the
arch/powerpc/platforms/book3s/ directory and move VAS API code
there. Functionality is not changed.

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



	  VAS devices are found in POWER9-based and later systems, they

	  provide access to accelerator coprocessors such as NX-GZIP and

	  NX-842. This config allows the kernel to use NX-842 accelerators,

	  and user-mode APIs for the NX-GZIP accelerator on POWER9 PowerNV

	  and POWER10 PowerVM platforms.



	  If unsure, say "N".
