APM: Avoid calling 'setOutputDevices' after adding output for HIDL
Legacy systems suffer from user-perceivable audio dropouts
during device switching. Since forcing of the patches is only
necessary on AIDL HALs, skip the call to 'setOutputDevices'
on previous versions. Since prior to AIDL HAL introduction
all major SoC vendors used legacy HAL version below '3', a check
for the primay HAL version should suffice.
