Skylander Portal: Trap Team Audio Transfers

[deReeperJosh]

Should fix #12887

Audio transfers are 64 bytes long (32 x 16 bit audio samples, 8khz mono), but the current code ensures the buf size is 32 only for interrupt transfers. This fix should let users play through Trap Team with the Emulated Portal, by allowing 64 byte transfers and not returning the status of the portal if it is an audio transfer.

Note that this is untested, it is simply based on the work I did within Dolphin to implement the same.

Hmm I didn't realize there were actually interrupt output towards the device.
Maybe separating the check depending on the endpoint used.
Check if (!(pipe.endpoint & 0x80)) to see if it's an output endpoint then the size check==0x40 for output endpoint only?

Yeah that makes sense - I was able to test this in the end on my Mac and it did not fix the issue, so will just go back through and make sure everything else is working as expected before adding that check in

Had to take some time away from this but have come back, it would actually appear that the endpoint for audio is 0x02, and everything else is 0x81. Have built and tested this locally as working - will rebase shortly :)
