kernel: RGA 2D accelerator ported (open-source vendor driver) — verified

Browse Source 
Ported the vendor multicore RGA char-dev driver (drivers/video/rockchip/rga3/,
CONFIG_ROCKCHIP_MULTI_RGA) to 6.18 — WardenOS's librga uses /dev/rga, not V4L2.
On warden-c8a3: rga2 probe successful, hw_version 3.3.87975, /dev/rga +
/dev/dma_heap present. This is the CPU-savings 2D accelerator (LVGL UI offload).

6 mechanical 5.10->6.18 API fixes (platform remove->void, hrtimer_init->
hrtimer_setup, iommu_map* gfp arg, get_user_pages_remote vmas arg, MAX_ORDER
compat, MODULE_IMPORT_NS string). CMA via the default 64 MiB pool +
DMABUF_HEAPS_CMA (a custom linux,cma DT node hangs boot). Recipe + deltas in
rga/PORT-DONE.md. All open source (vendor C source).
