Make Ipod Nano use packed 16 bit IIS FIFO transfers as well.

Finally get packed samples to work in a nice way on H10 in IIS mode. Add some more register defs.

Use halfword IIS FIFO mode for H10. Won't save interrupts but seems it should be the DMA compatible mode. Setup pcm-pp.c to ease evaluating setting up PortalPlayer targets for DMA audio and for building an inventory of proper I2S settings and transfer sizes for all.

Unify PCM interface just above the hardware driver level for all targets including the sims. Perform lockout of audio callback when changing states. Weird new playback or recording trouble? Check before and after this revision first though things seem quite sound.

PP502x: Make RAM physical addresses uncached. Cache the flash ROM on targets with one. Kill all the now unneeded cache flushing and i2s tweaking on e200 so clicking is no worry. Write the driver framebuffer at uncached addresses. Recording monitoring may be a little noisy in the left channel for the moment when not boosted and will be addressed. All seems to work as advertised including flash ROM dump.

I2S buffer level adjustment is not necessary on c200 as there is no memory mapped framebuffer that requires constant cache flushing like on e200.

Sansa c200 port. Rockbox works with sound. Several features are disabled including some lcd options, FM radio, recording, and all plugins. Loading the OF from the Rockbox bootloader does not work.

Reenable scaling on Sansa since a reasonable solution to clicks has been found.

e200: Use 16-16 L-R pairs when writing to the TX FIFO. Kill the channel swapping and clicks. Reduce number of FIQs. Should be adaptable to iPods and other PP targets in a few minutes work, eh?
