cec: TV could fail to handle one touch play [1/1]

PD#SWPL-185469
BUG:367525039

Problem:
If the <Active Source> message is received before TV receives
the SCREEN_ON broadcast, this message will be processed directly
in ActiveSourceHandler and results in a failure to switch source.
The root cause is that the mTvInputs variable is not cleared
in HdmiCecLocalDevice#disableDevice, since the tv input callback
is cleared before the clearing of hdmi device info list.
Besides, if the TV device adds the source device's HdmiDeviceInfo
with only <Active Source> message, it could fail to add the related
TvInputInfo to TvInput Framework.

Solution:
1.Clear the tv inputs saved in local tv device during standby.
2.Set valid port id to the HdmiDeviceInfo created by <Active Source>
message.
