[PATCH 3/5] drm/imagination: Update RISC-V firmware header

[Alexandru Dadu]

From: Alessio Belle <alessio.belle@xxxxxxxxxx>

Make RISC-V firmware header arch-independent. This header file contains
definitions common to all PowerVR architectures starting from Rogue, so
rename both the file and its contents to reflect this.
Add a _fw_ component to the filenames of risc-v internal firmware
headers to ensure that firmware-related files have the pvr_fw_ prefix.
