svga: clarify sys value -> input register mapping
We translate TGSI system value registers to VGPU10 input registers.
Add a comment and set file = TGSI_FILE_INPUT. That's not stricly
necessary since we map both TGSI_FILE_INPUT and TGSI_FILE_SYSTEM_VALUE
to VGPU10_OPERAND_TYPE_INPUT, but this makes the code a bit more
understandable.
