freedreno/a6xx: vsc size calculations
This still comes up with some fairly conservative sizes:
pre-resize VSC_PRIM_STRM_PITCH to: 0x1c000
pre-resize VSC_DRAW_STRM_PITCH to: 0x4000
pre-resize VSC_PRIM_STRM_PITCH to: 0x20000
pre-resize VSC_PRIM_STRM_PITCH to: 0x24000
pre-resize VSC_PRIM_STRM_PITCH to: 0x28000
pre-resize VSC_PRIM_STRM_PITCH to: 0x2c000
pre-resize VSC_PRIM_STRM_PITCH to: 0x30000
vs sizes based on overflow detection:
resized VSC_PRIM_STRM_PITCH to: 0x2080
resized VSC_PRIM_STRM_PITCH to: 0x4100
resized VSC_DRAW_STRM_PITCH to: 0x880
But slightly lower compared to what blob comes up with:
30: DI_PT_TRILIST(0,0-1919,1079):90:RM6_BINNING: 00010040 VSC_DRAW_STRM_PITCH: 0x10040
30: DI_PT_TRILIST(0,0-1919,1079):90:RM6_BINNING: 0003fc40 VSC_PRIM_STRM_PITCH: 0x3fc40
