video/drm: vop2: enable vop urgency signal output for rk3576

The urgency signal can improve the performance of VOP accessing DDR, since VP0
support 4K120hz output, it usually needs high performance and bandwidth, so it's
enabled at RK3576 VP0.

RK3576 VP0 has 8 lines post linebuffer, when full post line buffer is less 4,
the urgency signal will be set to 1, when full post line buffer is over 6, the
urgency signal will be set to 0.

1.If not to check the return value of display_get_edid_mode()
in bridge mode, the following check logic will be
entered:

if (ret && !state->force_output)
goto deinit;

And the case will be mistaken as force output and goto
deinit, which causes no display output.
2.Move the rockchip_bridge_mode_set() before the display
information logs, because the display mode may be
initialized in the function.
