drm/rockchip: dsi2: support disable hold mode in cmd mode

Browse Source 
when dsi controller work in cmd mode, it will tell vop work in
hold mode and must config te signal for vop.

when rk3588 dsi interface connect to rkx111 and work in cmd mode,
rkx111 will not provided a te signal, so it need disable hold
mode and transfer this config to vop.
