Subject: [PATCH v2 2/2] Bluetooth: btnxpuart: Add support for ISO packets

This enables btnxpuart driver to handle ISO RX packet when DUT is
configured as audio sink.

Tested IW612 on iMX8MMini platform and BlueZ-5.77 as follows:
1) Configured DUT with bap_bcast_sink role in pipewire configuration file.
2) Started pipewire and DUT is able to sync with Broadcast source through
pipewire.
3) ISO data RX is seen in btmon.
4) Audio/Music is heard on audio jack.
