zhou.han 04da30af11 drm: Optimize encoder_atomic_check flow [1/1] ...

PD#SWPL-183146

Problem:
On RDK-S7D, westeros did not set the attr property when
switching from 1080P to 2160P on the UI. 2160p60hz+444,10bit
is an invalid combination, causing atomic_check fail and
the TV display black screen.

Solution:
The flow matching mode and attr is moved to the check flow.
meson_hdmitx_encoder_atomic_mode_set api keep in the commit flow,
because vinfo is updated here.If it is moved to the DRM check
flow, it may cause timing issues and lose vsync.

Verify:
S7D/OHM

Test:
DRM-TX-130
