[PATCH] ASoC: UDA1380: refactor device registration

[Philipp Zabel <philipp.zabel@gmail.com>]

This patch mostly follows commit 5998102b9095fdb7c67755812038612afea315c5
"ASoC: Refactor WM8731 device registration" to make UDA1380 use standard
device instantiation. Similarly, the I2C device registration temporarily
moves into the magician machine driver before it will find its final
resting place in the board file.

At the same time, platform specific configuration is moved to platform data
and common power/reset GPIO handling moves into the codec driver.
