drm/rockchip: vop: add cycles_per_pixel check for both rgb and mcu interfaces

Browse Source 
The RGB interface also supports formats that have multiple cycles per
pixel, such as MEDIA_BUS_FMT_RGB888_3X8, MEDIA_BUS_FMT_RGB565_2X8_LE,
and so on. And the &drm_display_mode.crtc_clock should be multiplied by
the return value of rockchip_drm_get_cycles_per_pixel().

Fixes: 3cb261be89 ("drm/rockchip: drv: fix the dclk calculation of mcu interface")
