Report on MOBILE_API.xml issues(inconsistent range)

[Yuki-Shoda-Nexty]

We propose correcting MOBILE_API.xml(inconsistent range)

In current MOBILE_API.xml, some of descriptions about actual operation of the Head Unit (HU) and setting values of related parameters are inconsistent.
By fixing such descriptions, we can provide more accurate RPC documents for SDL developers.
The target items are below two parameters.

1. Modification of parameter maxDuration of PerformAudioPassThru.
   Since it takes 1-2 sec to start recording by the onboard Mic after the RPC is sent, hence it is inconsistent that the minimum value of maxDuration is 1 ms.
   It is appropriate that the minimum value of maxDuration is 2000 or 3000 ms at least.

2. Correction of the parameter syncFileName of `PutFile
   Since the maximum length of syncFileName in the RPC SetAppIconDeleteFile is 500, hence it is inconsistent that the maximum length of syncFileName is 255.
   It is appropriate that the maximum length of syncFileName is unified into same value 500.

Modify as shown below.

1. Modification of parameter maxDuration of PerformAudioPassThru.

-        <param name="maxDuration" type="Integer" minvalue="1" maxvalue="1000000" mandatory="true">
+        <param name="maxDuration" type="Integer" minvalue="3000" maxvalue="1000000" mandatory="true">
             <description>The maximum duration of audio recording in milliseconds. </description>
          </param>

2. Correction of the parameter syncFileName of `PutFile

-        <param name="syncFileName" type="String" maxlength="255" mandatory="true">
+        <param name="syncFileName" type="String" maxlength="500" mandatory="true">
             <description>File reference name.</description>
          </param>
