ALSA: drop outdated and broken sa11xx-uda1341 driver
It depends on L3 support from 2.4 kernel (CONFIG_L3) that never got merged into mainline. Since there's no way to use it on any of supported machines (iPaq h3100 or h3600), better drop it for now. It can be reimplemented later using ASoC infrastructure (there's already a driver for uda1341 codec in mainline, so only CPU and machine parts need to be written).

24/***************************************************************************************************
25*
26* To understand what Alsa Drivers should be doing look at "Writing an Alsa Driver" by Takashi Iwai
27* available in the Alsa doc section on the website
28*
29* A few notes to make things clearer. The UDA1341 is hooked up to Serial port 4 on the SA1100.
30* We are using SSP mode to talk to the UDA1341. The UDA1341 bit & wordselect clocks are generated
31* by this UART. Unfortunately, the clock only runs if the transmit buffer has something in it.
32* So, if we are just recording, we feed the transmit DMA stream a bunch of 0x0000 so that the
33* transmit buffer is full and the clock keeps going. The zeroes come from FLUSH_BASE_PHYS which
34* is a mem loc that always decodes to 0's w/ no off chip access.
35*
36* Some alsa terminology:
37* frame => num_channels * sample_size e.g stereo 16 bit is 2 * 16 = 32 bytes
38* period => the least number of bytes that will generate an interrupt e.g. we have a 1024 byte
39* buffer and 4 periods in the runtime structure this means we'll get an int every 256
40* bytes or 4 times per buffer.
41* A number of the sizes are in frames rather than bytes, use frames_to_bytes and
42* bytes_to_frames to convert. The easiest way to tell the units is to look at the
43* type i.e. runtime-> buffer_size is in frames and its type is snd_pcm_uframes_t
44*
45* Notes about the pointer fxn:
46* The pointer fxn needs to return the offset into the dma buffer in frames.
47* Interrupts must be blocked before calling the dma_get_pos fxn to avoid race with interrupts.
48*
49* Notes about pause/resume
50* Implementing this would be complicated so it's skipped. The problem case is:
51* A full duplex connection is going, then play is paused. At this point you need to start xmitting
52* 0's to keep the record active which means you cant just freeze the dma and resume it later you'd
53* need to save off the dma info, and restore it properly on a resume. Yeach!
54*
55* Notes about transfer methods:
56* The async write calls fail. I probably need to implement something else to support them?
