Subject: [PATCH] Fix Sound Amplifier does not have 'Open XXX' button

SettingsMainSwitchPreference does not allow hide switch bar. For support
this launch preference, we hide the SettingsMainSwitchPreference and add
new preference into the list.

Bug: 184711985
Test: Manual testing
Change-Id: I293800e83aafb387e0bb0a4988af774b56f508e6
