Summary 08466: fsa1fx [spmanbow]: Choppy scrolling

Scrolling is noticeably choppier when the game is played with this driver. Even the nms8250 driver exhibits smoother scrolling.
Steps To Reproduce Launch fsa1fx with msx2_cart:spmanbow.

This is common for all MSX2+ machines with V9958 VDP which has a hardware horizontal scroll function. It's not fully emulated.
