By replacing VGA_VSTATUS_CNTL by VGA_RENDER_CONTROL__VGA_VSTATUS_CNTL_MASK,
we also need to fix its usage in GMC6.

Note: VGA_VSTATUS_CNTL's binary value was inverted in dce_6_0_sh_mask.h,

afcdf51d97 drm/amd/display: Protect FPU in dml2_init()/dml21_init() 
Commit 7da55c27e7 ("drm/amd/display: Remove incorrect FP context
start") removes the FP context protection of dml2_create(), and it said
"All the DC_FP_START/END should be used before call anything from DML2".

However, dml2_init()/dml21_init() are not protected from their callers,
causing such errors:

c0dd8a9253 drm/amdgpu/dma_buf: fix page_link check 
The page_link lower bits of the first sg could contain something like
SG_END, if we are mapping a single VRAM page or contiguous blob which
fits into one sg entry. Rather pull out the struct page, and use that in
our check to know if we mapped struct pages vs VRAM.
