If the cluster sub wins are enabled, there will be POST_BUF_EMPTY
errors after entering the PSR mode, because cluster main wins are
disabled while the sub wins still are active. The patch can help
avoid these unexpected POST_BUF_EMPTY errors.

Psr mode can help reduce power consumption when using the mcu panel,
which supports to refresh the image on its own while it remains
unchanged.

According to the following commits:
commit 9d0e3cac35 ("drm/atomic: Allow vblank-enabled + self-refresh "disable"")
commit 2bdba9d4a3 ("drm/rockchip: vop: Leave vblank enabled in self-refresh")
It is better to leave vblank enabled after entering the PSR mode, in
order to ensure that the vblank APIs (like DRM_IOCTL_WAIT_VBLANK) can
work in PSR mode. User space is not aware when the display system is
already in PSR mode, so this appears to be an API violation.
Without this patch, there may be a warning according to the following
check in drivers/gpu/drm/drm_atomic_helper.c:
static void
disable_outputs(struct drm_device *dev, struct drm_atomic_state *old_state)
{
......
ret = drm_crtc_vblank_get(crtc);
/*
* Self-refresh is not a true "disable"; ensure vblank remains
* enabled.
*/
if (new_crtc_state->self_refresh_active)
WARN_ONCE(ret != 0,
"driver disabled vblank in self-refresh\n");
else
WARN_ONCE(ret != -EINVAL,
"driver forgot to call drm_crtc_vblank_off()\n");
if (ret == 0)

The &link_train.link_rate and &link_train.lane_count are used as the
max_link_rate and max_lane_count to check the bandwidth limitation
, select output format and so on. However, they both also are used as
the actual link_rate and lane_count for the eDP controller and phy.
So we add &link_train.max_link_rate and &link_train.max_lane_count
in order to avoid the confusion in the use of above variables.
On the other hand, some unexpected errors will occur without this
patch in some cases.
When I test the PSR function of eDP panel module NE160QAM-NX1, the
link rate will be set to the 8.1G, which is the max supported link
rate of this module, after exiting the PSR state, but it should be
5.4G corresponding to 3840x2400p60 resolution.
analogix_dp_detect(): set the &link_train.link_rate to 8.1G
-> analogix_dp_fast_link_train():
use the &link_train.link_rate as the previous link config
-> analogix_dp_set_link_bandwidth()
-> phy_configure():
error: invalid link_rate config 8.1G

RK3588/RK3576 hdmi color format setting and dsc mode setting are
the same mask in the same register. If dsc is enabled for hdmi in
uboot, what color is hdmi output in uboot that cannot be obtained
from this register in kernel.
Since hdmi in dsc mode always sends avi infoframe, color format
of hdmi output in uboot can be read from the avi register.

maybe keep previous sink's when the hdmi is connected to another
