[PATCH v3 08/17] video: rockchip: vop: Add dsp offset support

[Jagan Teki <jagan@amarulasolutions.com>]

From: Jagan Teki <jagan@edgeble.ai>

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

Group the dsp register set via dsp_regs pointers so that dsp_offset
would point the dsp_regs to access for any changes in the offset value.
