Update the name of pvr_rogue_heap_config.h to pvr_heap_config.h to
prepare it for a more generic implementation that will have memory
sections defined for multiple GPU architectures.
Update the multi-arch common define names to a generic format.

This isn't really related to the rest and could be applied by itself, or split
if you need to send a v5 and this hasn't been applied yet.
Thanks,

- Rename the RISC-V firmware processor header adding an "internal"
suffix.
- Add guard to the RISC-V firmware processor header to prevent
accidental inclusion outside of the RISC-V firmware specific logic.

This header file contains definitions common to all PowerVR

From: Alessio Belle <alessio.belle@imgtec.com>
Ensure all accesses to the META firmware interface are done via the
generic firmware interface.
To achieve this:
- Introduce a new function to the firmware processor table to remove
the last direct access to the META firmware interface from
outside of the generic firmware logic.
- Remove the META firmware interface header.
- Rename the META firmware processor header adding an "internal" suffix.
- Add guard to the META firmware processor header to prevent accidental
inclusion outside of the META firmware specific logic.
- Add a multi_dm_thread_assoc property to struct pvr_fw_defs to isolate
that behaviour from the architecture.
