Fix doing silent update,power cut/restoration,screen is turned on

[Description]
1. In the current code, when tv enter recovery mode, it will
write "boot-recovery" into the BCB command field by default.
This is a protection mechanism to ensure that tv can re-enter
recovery mode continues OTA upgrade after power cut/power restoration.
So, when re-enter recovery mode, since there is no "quiescent"
in the boot parameters, the screen will turn on.

2. And we hope the screen will be turned off when tv re-enter
recovery mode to continue OTA upgrade.

3. We made the following modify:
In reocvery mode,According to GetBoolProperty
"ro.boot.quiescent"to determine whether it is a quiescent
boot this time,and then write "boot-recovery, quiescent"
or"boot-recovery" accordingly.

[Test Report]
1.boot up ok.
2.silent update ok.
(the screen is turned off when interrupting/
resume or complete the upgrade)
3.OTA update ok.
(the screen is turned on when interrupting/
resume or complete the upgrade)
