mingxiu.sun 331f4ebfcb vdin1: hist and screenshot are abnormal [1/1] ...

PD#SWPL-143500

Problem:
1.The hist related register is initialized when vdin_start_dec,
the hist value of the DG is overwritten after the system starts
2.The abnormal frame is intercepted before the video signal stabilizes
3.The probability of hist's width and height is 0
4.When closing the front-end channel,
setting 0x1df9 and 0x2783 to 0 results in abnormal hist function

Solution:
1.For txhd2, remove the hist initial configuration from vdin_set_all_regs
2.Frames are dropped when an abnormal frame is found for vdin1
3.Add 20ms delay when the hist register completes
4.After closing the front-end channel, configure the hist register

Verify:
txhd2 kernel5.15
