[PATCH 07/17] video: rockchip: vop: Add win offset support

[Jagan Teki]

From: Jagan Teki <ja...@edgeble.ai>

Unlike RK3399, RK3288 the Newer Rockchip SoC's like RK3328 have
different offsets for win registers.

Group the win register set via win_regs pointers so that win_offset
would point the win_regs to access for any changes in the offset value.
