The fastrpc driver has support for 5 types of remoteprocs. There are
some products which support GPDSP remoteprocs. Add changes to support
GPDSP remoteprocs.

We have already made the driver look silly here, Lets not add domain ids
for each instance, which is not a scalable.
Domain ids are strictly for a domain not each instance.

Can you try this patch: only compile tested.

Subject: [PATCH] misc: fastrpc: cleanup the domain names
Currently the domain ids are added for each instance of domain, this is
totally not scalable approch.
Clean this mess and create domain ids for only domains not its
instances.
This patch also moves the domain ids to uapi header as this is required
for FASTRPC_IOCTL_GET_DSP_INFO ioctl.
