regulator: Add support for ramp delay

Changing voltage and enabling regulator might require delays so the
regulator stabilizes at expected level.

Add support for "regulator-ramp-delay" binding which can introduce
required time to both enabling the regulator and to changing the
voltage.

sound: Add support for Intel HDA

The Intel High-definition Audio is a newer-generation audio system which
provides for transfer of a large number of audio stream, each containing
up to 16 channels.

Add support for HDA as a library which can be used by other drivers.
U-Boot currently uses only two channels (stereo).
