[PATCH v13 4/4] drm/imagination: Enable PowerVR driver for RISC-V

[Michal Wilczynski <m.wilczynski@samsung.com>]

Several RISC-V boards feature Imagination GPUs that are compatible with
the PowerVR driver. An example is the IMG BXM-4-64 GPU on the Lichee Pi
4A board. This commit adjusts the driver's Kconfig dependencies to allow
the PowerVR driver to be compiled on the RISC-V architecture.

By enabling compilation on RISC-V, we expand support for these GPUs,
providing graphics acceleration capabilities and enhancing hardware
compatibility on RISC-V platforms.

The RISC-V support is restricted to 64-bit systems (RISCV && 64BIT) as
the driver currently has an implicit dependency on a 64-bit platform.

Add a dependency on MMU to fix a build warning on RISC-V configurations
without an MMU.
