[patch 1/4] xtensa: move definition of irq numbers to platform header

[Daniel Glöckner]

Alsa SoC drivers traditionally provide the platform specific code as
separate modules. Move the list of irq numbers to a header file to
allow it being used in several files.

[patch 3/4] xtensa: prepare s6105 platform for I2S

[Daniel Glöckner]

This patch routes the I2S irq, powers up the I2S block and resets the
I2S codec.

Resetting of the codec can't be moved to the sound driver as the reset
line affects another chip as well.
