gpu/drm: remove the powerpc hack in drm_legacy_sg_alloc
The non-cached vmalloc mapping was initially added as a hack for the
first-gen amigaone platform (6xx/book32s), isn't fully supported upstream,
and which used the legacy radeon driver together with non-coherent DMA.
However this only ever worked reliably for DRI .
Remove the hack as it is the last user of __vmalloc passing a page
protection flag other than PAGE_KERNEL and didn't do anything for other
platforms with non-coherent DMA.
