This patch adds support for the UDA134X codec and a sound card
definition for one of these UDAs connected to the s3c24xx. It is
*heavily* based on the one made by Zoltan Devai but:

1 since the UDA is the only use of the L3 protocol I can find I just
embedded a stripped-down L3 bit-banging algorithm from the original
RMK work. It is really small.

2 the driver has the possibility to specify the pins used by codec
via platform data so it can work on SMDK2410, SMDK2440 or any custom

3 it tries to guess the right clock source and divider so it is not tied
to a particular crystal used.

4 it fixes some bugs.
