* Lots of codec updates

* Lots of codec updates
* New kconfig version (from latest Linux kernel)
* Sound is finally starting to work on the BT-200 phone!!!

Re. sound:  When it boots the echo program that sends 1 kHz samples over the McBSP #1
it starts up silently.  The Codec has not been initialised at that time:

Channel 0 registers (slave 0x40): 1A=90 2A=20 3C=88 3D=c0 3A=01 3B=40 4A=08 4B=9e 5A=00 5B=40 5C=bf 5D=c0 6A=02 6B=82
Channel 1 registers (slave 0x41): 1A=90 2A=20 3C=88 3D=c0 3A=01 3B=40 4A=08 4B=9e 5A=00 5B=40 5C=bf 5D=c0 6A=00 6B=80

Then, run the following commands:

./bin/i2cp/aic2x-config /dev/i2c-2 0x40 0x49 0xa0 0x01 0x40 0x88 0xff 0x08 0x9e 0x1f 0x40 0xbf 0xc0 0x02 0x82
./bin/i2cp/aic2x-config /dev/i2c-2 0x41 0x49 0xa0 0x31 0x60 0x88 0xff 0x08 0x9e 0x12 0x50 0xbf 0xc0 0x00 0x80

This will raise sound (not through DMA but "manual" writes to McBSP); the codec reads:

Channel 0 registers (slave 0x40): 1A=49 2A=a0 3A=01 3B=40 3C=88 3D=ff 4A=08 4B=9e 5C=bf 5D=c0 5A=1f 5B=40 6A=02 6B=82
Channel 1 registers (slave 0x41): 1A=49 2A=a0 3A=31 3B=60 3C=88 3D=ff 4A=08 4B=9e 5C=bf 5D=c0 5A=12 5B=50 6A=00 6B=80

Note that the volume is not always the same; apparently there is still some form of
sync problem.  Things to explore are now:

1. Whether the TLV should be reset before setting up McBSP #1
2. Whether the data to the Codec is stable as long as SCLK is low
3. Whether FS changes when SCLK is high (max 6 ns after going up, no min specified)
