No Audio heard in FM Speaker when FM record and FM speaker are on simultaneously
With default values for maxActiveCount and maxOpenCount,
FM app is unable to record and play FM audio on speaker simultaneously
since it uses application loop back(AudioRecord->AudioTrack)
to route FM audio to non-default devices(Speaker)
Add attributes maxActiveCount="2" and maxOpenCount="2" to mixPort "primary input"

* Speaker isn't properly calibrated with ACDB from O-based MIUI (while
it was on N), pop is heard when disabling speaker.
* MIUI has speaker protection enabled, hence this route isn't even
used by Xiaomi. However, with speaker protection enabled on Lineage,
the volume curve became very strange, maybe Xiaomi uses Dirac audio
effect to address this issue on MIUI, but it's not supported on AOSP.
* Fortunately voice speaker seems to be properly calibrated, so apply
that route to fix the issue.
* Voice speaker gain in ACDB seems to be lower than speaker, so
slightly increase gain in mixer paths to make it sound like a "normal"
speaker.
