amdgpu,radeon: Add workarounds for the Spacemit K1-X RISC-V platform ...
1. In various GMC versions (v6-v11), the DMA address mask is
reduced to 34 bits. This is necessary because PCIe devices on the
Spacemit K1-X platform support a maximum of 34-bit physical addressing.
2. In amdgpu_ttm.c, force the use of the `ttm_write_combined` cache mode.
This is required because the K1-X platform lacks PCIe cache coherency.
3. In radeon_ttm.c and amdgpu_vram_mgr.c, switch the caching for
IO memory to `ttm_uncached`.This is done to guarantee data correctness
during VRAM access on this platform.
