Subject: [PATCH v1] misc: fastrpc: Move fastrpc driver to misc/fastrpc/

Move fastrpc.c from misc/ to misc/fastrpc/. New C files are planned
to be added for PD notifications and other missing features. Adding
and maintaining new files from within fastrpc directory would be easy.

Example of feature that is being planned to be introduced in a new C
file:
https://lore.kernel.org/all/20240606165939.12950-6-quic_ekangupt@quicinc.com/
